Conditions and notes
Temperature and temperature difference are distinct quantities.
Temperature readings follow K = °C + 273.15 and °F = 1.8 × °C + 32. Temperature differences have no offset. A temperature of 10 °C is 50 °F, while a difference of 10 °C is a difference of 18 °F. Absolute zero is 0 K. Blank cells indicate that a different quantity is not shown on that row, not a value of zero.
