Temperature conversion is fundamental in weather forecasts, healthcare, and engineering. When watching US news, you convert Fahrenheit (°F) to Celsius (°C). In aerospace and low-temperature physics, Kelvin (K) is the standard for absolute temperature.
History & Background
Early thermometers lacked a unified scale. In 1714, Daniel Fahrenheit invented the mercury thermometer. In 1742, Swedish astronomer Anders Celsius proposed a centigrade scale based on the freezing and boiling points of water.
Conversion Details
Unlike length or weight, temperature conversion is not a simple ratio — it has an offset.
Common conversions: 0 °C = 32 °F, 100 °C = 212 °F, 0 °C = 273.15 K.
