About the Temperature converter
Temperature scales do not share a zero point, so conversion needs an offset as well as a scale factor. Celsius and Kelvin have the same step size; Fahrenheit steps are 5/9 the size.
Useful anchors: water freezes at 0 °C (32 °F, 273.15 K) and boils at 100 °C (212 °F) at sea level. −40 is the same in Celsius and Fahrenheit.
