In these conversion tables, brackets are used to indicate the number of units of the involved temperature, on the scale mentioned between the brackets,. I.e. [°C] means the temperature T at stake is: T = [°C]°C = [°F]°F = [K]K etc.

* Note that absolute zero temperatures outside of the Kelvin system are from conversion purposes only. True absolute zero values in non-Kelvin systems are infinitely negative (-∞).
** Normal human body temperature is 36.8 Â°C ±0.7 Â°C, or 98.2 Â°F ±1.3 Â°F. The commonly given value 98.6 Â°F is simply the exact conversion of the nineteenth-century German standard of 37 Â°C. Since it does not list an acceptable range, it could therefore be said to have excess (invalid) precision. Here's a list of various measurements.
Some numbers in this table have been rounded off.
