Temperature Converter

To convert Celsius to Fahrenheit, multiply the Celsius temperature by 9/5 (1.8) and add 32. Formula: °F = (°C × 9/5) + 32. For example, 20°C × 1.8 + 32 = 68°F.

To convert Fahrenheit to Celsius, subtract 32 from the Fahrenheit temperature and multiply by 5/9. Formula: °C = (°F − 32) × 5/9. For example, (68°F − 32) × 5/9 = 20°C.

37°C is 98.6°F. This is the standard normal human body temperature. The conversion is (37 × 9/5) + 32 = 98.6°F.

100°F is approximately 37.78°C. The conversion is (100 − 32) × 5/9 = 37.78°C.

0°C is 32°F. This is the freezing point of water. The conversion is (0 × 9/5) + 32 = 32°F.

100°C is 212°F. This is the boiling point of water at sea level. The conversion is (100 × 9/5) + 32 = 212°F.

Normal human body temperature is approximately 37°C (98.6°F). However, normal ranges can vary from 36.1°C to 37.2°C depending on the individual, time of day, and activity level.

Normal human body temperature is approximately 98.6°F (37°C). A normal range is typically considered between 97°F and 99°F depending on factors like age, activity, and time of measurement.

The US continues to use Fahrenheit due to historical adoption before the metric system became widespread. Fahrenheit is also preferred by many for weather reporting as it provides a more granular scale for air temperature perception.

Celsius (also called Centigrade) is used by almost every country worldwide for everyday temperature measurement, including all of Europe, Asia, Africa, South America, and Australia. Only the US, Bahamas, Belize, and a few others use Fahrenheit.

Room temperature is typically considered to be between 20°C and 22°C (68°F–72°F). However, comfortable room temperature can vary from 18°C to 24°C depending on personal preference and humidity.

Room temperature is typically considered to be between 68°F and 72°F (20°C–22°C). This range is commonly used for indoor comfort in homes, offices, and commercial spaces.

To convert Kelvin to Celsius, subtract 273.15 from the Kelvin temperature. Formula: °C = K − 273.15. For example, 300 K − 273.15 = 26.85°C.

To convert Celsius to Kelvin, add 273.15 to the Celsius temperature. Formula: K = °C + 273.15. For example, 25°C + 273.15 = 298.15 K.

Absolute zero is the lowest possible temperature where all molecular motion stops. It is 0 Kelvin (−273.15°C or −459.67°F). At this temperature, a system has minimum possible thermal energy.

Different temperature scales were developed historically for different purposes. Fahrenheit was created for everyday weather measurement. Celsius was designed around water's freezing and boiling points. Kelvin is used in science as an absolute thermodynamic scale.

All three scales (Celsius, Fahrenheit, Kelvin) are equally accurate — they just use different reference points. Kelvin is the SI standard for scientific measurements because it starts at absolute zero. Celsius is most commonly used worldwide for daily life.

Online temperature converters using standard formulas are perfectly accurate. The conversion formulas (e.g., °F = °C × 9/5 + 32) are exact mathematical relationships, so results are precise to as many decimal places as displayed.

The freezing point of water at sea level is 32°F (0°C). This is a key reference point on the Fahrenheit scale.

The boiling point of water at standard sea-level pressure is 100°C (212°F). This decreases at higher altitudes due to lower atmospheric pressure.
