Unlike most online calculators that require you to select "From" and "To" from a dropdown menu, our tool is fully synchronized. Just type a number into any unit box, and the other two will update in real-time.
The average normal body temperature is generally accepted as 37°C or 98.6°F. However, normal body temperatures can range slightly from 36.1°C (97°F) to 37.2°C (99°F) depending on the individual, time of day, and activity level.
Celsius and Fahrenheit intersect at -40 degrees. So, -40°C is exactly equal to -40°F!
Absolute zero is the lowest possible theoretical temperature, where all atomic motion stops. It is defined as 0 Kelvin, which is equivalent to -273.15°C or -459.67°F. Notice that Kelvin does not use a degree symbol (°), as it is an absolute scale rather than a relative one.
