Como usar esta calculadora

  1. Enter a temperature (negative values are allowed).
  2. Choose the scale you have and the scale you want.

Fórmula

Temperature scales differ in both size of degree and zero point, so conversion uses an offset as well as a factor.

°F = °C × 9/5 + 32
°C = (°F − 32) × 5/9
K = °C + 273.15
°R = °F + 459.67

Examples

  1. 100 °F → (100 − 32) × 5/9 = 37.78 °C.
  2. 20 °C → 20 × 1.8 + 32 = 68 °F.
  3. −40 °C = −40 °F, where the scales meet.

Perguntas frequentes

What is normal body temperature?

About 37 °C (98.6 °F), though healthy values range roughly from 36.1 to 37.2 °C.

What is absolute zero?

0 K = −273.15 °C = −459.67 °F, the lowest possible temperature.

Why does Kelvin have no degree sign?

Kelvin is an absolute SI unit, so it's written simply as K.
