Temperature measurement.

A temperature of absolute zero is called 0 K on the kelvin scale and −273.15 °C on the Celsius scale, therefore a translation factor of −273 °C is needed. So we're basically multiplying by one, which is the same as doing nothing, and subtracting 273. The reverse conversion is equally simple. °C ← K.
