The thermometer above shows the exact temperature at your location using live atmospheric data. It also displays feels like temperature, humidity, wind speed, and pressure to provide a complete understanding of current weather conditions. Temperature near me is updated continuously from the nearest weather observation station to give you an accurate real-time reading.
The feels like temperature — also called apparent temperature — reflects how hot or cold conditions actually feel on human skin, taking into account wind chill at cold temperatures and heat index at warm temperatures. In cold weather, wind makes the air feel significantly colder than the thermometer reading because it strips away the layer of warm air near your skin. In hot, humid weather, high humidity prevents sweat from evaporating efficiently, making the temperature feel hotter than the actual reading. This is more accurate than raw temperature alone and is critical for understanding real-world conditions.
Temperature varies based on geography, elevation, time of day, season, and atmospheric conditions. Coastal areas are moderated by the sea and rarely reach temperature extremes. Deserts experience extreme diurnal ranges — very hot days and surprisingly cold nights. Cities are typically warmer than surrounding countryside due to the urban heat island effect. Elevation reduces temperature at a rate of approximately 6.5°C per 1,000 metres of altitude gain.

A thermometer is a scientific instrument used to measure temperature — the degree of heat or cold of a substance or environment. The word thermometer comes from the Greek thermos (hot) and metron (measure). Thermometer meaning in everyday use encompasses any device that measures and displays temperature, from clinical body thermometers to outdoor weather thermometers to cooking probe thermometers. The thermometer definition in physics refers to an instrument that measures thermal energy by detecting changes in a temperature-sensitive property such as liquid volume, electrical resistance, or infrared radiation.
An online thermometer is a web-based tool that displays real-time temperature for your location or any city using live weather station data. Unlike a physical outdoor thermometer that only reads conditions at one fixed location, an online thermometer can check current temperature anywhere in the world instantly. This page provides a live online thermometer that works on any device without requiring a physical instrument.
How to use a thermometer depends on its type. For a digital clinical thermometer: (1) Turn it on and wait for the ready signal. (2) For oral measurement, place the tip under the tongue and close your mouth. (3) Wait for the beep signal, typically 10–60 seconds. (4) Read the display — normal range is 36.1–37.2°C. (5) Clean with alcohol after use. For how to use a thermometer outdoors: mount it in a shaded, ventilated position at least 1.2 metres above ground, away from walls and direct sunlight for accurate ambient air temperature readings. For how to use a meat thermometer: insert the probe into the thickest part of the meat, away from bone or fat, and check against safe minimum internal temperature charts.
A mercury thermometer uses a glass tube containing liquid mercury. As temperature rises, mercury expands and rises up the tube against a calibrated scale. Mercury thermometers were the standard clinical and laboratory instrument for centuries due to their accuracy. Because mercury is toxic, mercury thermometers have been largely phased out of clinical and household use in favour of digital alternatives, though they remain in some laboratory applications.
A digital thermometer uses an electronic sensor — typically a thermistor or thermocouple — to measure temperature and displays the result on a digital screen. Digital thermometers are fast, accurate, affordable, and safe. They are the most common type of clinical thermometer today and are widely used as room thermometers, outdoor thermometers, meat thermometers, and food thermometers.
An infrared thermometer measures temperature without physical contact by detecting infrared radiation emitted by a surface. Also called a non-contact thermometer or forehead thermometer when used clinically, infrared thermometers became widely used during the COVID-19 pandemic for rapid, hygienic temperature screening. They are also used in industrial settings to measure surface temperatures of equipment, electronics, and food.
A clinical thermometer is specifically designed to measure human body temperature. Clinical thermometers include oral, rectal, ear (tympanic), forehead (temporal artery), and underarm (axillary) types. They have a narrow temperature range (typically 35–42°C) calibrated for human physiology. Modern clinical thermometers are almost all digital for safety, speed, and hygiene.
A Galileo thermometer is a decorative glass cylinder filled with liquid and containing glass spheres of slightly different densities. As temperature changes, the liquid's density changes, causing the spheres to rise or fall. The temperature is read from the lowest floating sphere. Galileo thermometers are named after Galileo Galilei though he did not actually invent this particular type — the design was created by later Florentine scientists inspired by his work.
An alcohol thermometer works on the same principle as a mercury thermometer but uses coloured alcohol instead of mercury. Alcohol thermometers are safer than mercury versions and can measure lower temperatures because alcohol freezes at −114°C, well below mercury's −39°C freezing point. They are commonly used as outdoor thermometers and in educational settings.
A bimetallic thermometer uses a coiled strip made of two different metals bonded together. Because the metals expand at different rates with temperature changes, the strip bends and moves a needle across a dial. Bimetallic thermometers are robust, require no power, and are widely used in cooking thermometers, oven thermometers, and industrial applications where durability is important.
A laboratory thermometer is a precision instrument used in scientific settings with a wide temperature range and high accuracy. Laboratory thermometers typically use mercury or alcohol in calibrated glass tubes and are designed for immersion in liquids or gases during experiments. Digital laboratory thermometers using thermocouples or platinum resistance thermometers (PTRs) are increasingly common in modern labs.
A thermocouple measures temperature by detecting the voltage generated at the junction of two different metals — the Seebeck effect. Thermocouples can measure extremely high and low temperatures and are used extensively in industrial processes, cooking equipment, and scientific research. Probe thermometers used in professional cooking often use thermocouple sensors for their speed and accuracy.
Normal body temperature for adults is 37°C (98.6°F) measured orally, though the healthy range is 36.1–37.2°C (97–99°F). Body temperature varies by measurement method: rectal temperature runs about 0.3–0.6°C higher than oral; ear temperature is similar to rectal; axillary (armpit) temperature runs about 0.3–0.6°C lower than oral. Temperature also varies by time of day — lowest in the early morning, highest in late afternoon. A fever is generally defined as a body temperature above 38°C (100.4°F).
| Condition | Temperature (°C) | Temperature (°F) |
|---|---|---|
| Hypothermia | Below 35°C | Below 95°F |
| Normal | 36.1–37.2°C | 97–99°F |
| Low-grade fever | 37.3–38°C | 99.1–100.4°F |
| Fever | 38–39°C | 100.4–102.2°F |
| High fever | 39–40°C | 102.2–104°F |
| Dangerous | Above 40°C | Above 104°F |
The thermometer was developed progressively by several scientists. Galileo Galilei invented a thermoscope — a device that showed temperature changes without a numerical scale — around 1593. Santorio Santorio added a numerical scale to create the first clinical thermometer around 1612. In 1714, Daniel Gabriel Fahrenheit invented the first modern mercury thermometer and introduced the Fahrenheit temperature scale. In 1742, Anders Celsius introduced the Celsius scale (originally with 0° at boiling and 100° at freezing, later inverted). Lord Kelvin proposed the absolute temperature scale (Kelvin) in 1848, with 0 K representing absolute zero (−273.15°C).
Three temperature scales are in common use. Celsius (°C) is the metric scale used worldwide for everyday temperature measurement. Water freezes at 0°C and boils at 100°C at standard pressure. Fahrenheit (°F) is used primarily in the United States. Water freezes at 32°F and boils at 212°F. Kelvin (K) is the scientific absolute temperature scale used in physics and chemistry. 0 K is absolute zero — the theoretical lowest possible temperature. The conversion formulas: °F = (°C × 9/5) + 32; °C = (°F − 32) × 5/9; K = °C + 273.15.
Room temperature is typically defined as 20–22°C (68–72°F), though comfort varies by individual and season. An indoor thermometer measures the ambient temperature inside a building, which differs from outdoor temperature due to heating, air conditioning, insulation, and solar gain through windows. Normal comfortable indoor temperatures are: living rooms 20–22°C, bedrooms 16–19°C, kitchens 18–20°C, and bathrooms 22–24°C. High indoor humidity combined with high temperature increases discomfort — this is why humidity is shown alongside temperature on this page.
Many people search for a thermometer app to check temperature on their phone. Most smartphones do not have a dedicated ambient air temperature sensor — the sensors inside phones measure the temperature of the device itself, not the surrounding air. Some older Android phones had built-in temperature sensors but these were phased out. The most accurate way to check current temperature on a phone is through an online thermometer like this page, which uses professional weather station data rather than phone sensors.
