Temperature: Celsius, Fahrenheit and Kelvin
Temperature is the one quantity here with an offset: Celsius and Fahrenheit are shifted against each other and Kelvin starts at absolute zero, so these conversions add rather than only multiply.
| °C | °F | K |
|---|---|---|
| -40 | -40 °F | 233.15 K |
| -20 | -4 °F | 253.15 K |
| -10 | 14 °F | 263.15 K |
| 0 | 32 °F | 273.15 K |
| 10 | 50 °F | 283.15 K |
| 20 | 68 °F | 293.15 K |
| 30 | 86 °F | 303.15 K |
| 37 | 98.6 °F | 310.15 K |
| 100 | 212 °F | 373.15 K |
At −40 °C and −40 °F both scales read the same value — the only point where they agree. 0 °C is 273.15 K and 32 °F; 37 °C (body temperature) is 98.6 °F. Absolute zero is 0 K, which is −273.15 °C.
