Anchors: water freezes at 0°C / 32°F / 273.15 K and boils at 100°C / 212°F; body temperature is 37°C / 98.6°F; −40° is the same in both C and F.

How to use

  1. Enter a temperature and its scale.
  2. Pick the target scale or swap.
  3. Read the result — all three scales are shown below.

Frequently asked questions

°F = °C × 9/5 + 32. Going the other way: °C = (°F − 32) × 5/9.

Science — it starts at absolute zero (−273.15°C), so it has no negative values. K = °C + 273.15.

Double the Celsius and add 30 — close enough for weather (exact uses ×1.8 + 32).
