About temperature interval units
A temperature difference is not the same as a temperature reading. A rise of 10 °C is a rise of 18 °F (not 50 °F), because only the size of the degree matters, not where zero sits. Use this converter for tolerances, temperature rises, ΔT in heat-transfer calculations and thermostat swings.
