Calculation for 212 °F
(212 − 32) × 5/9 = 180 × 5/9 = 100 °C.
For this input, 100 °C is exact; no decimal rounding is needed.
For a temperature reading, use °F = °C × 9/5 + 32, or °C = (°F − 32) × 5/9. Results are displayed to at most two decimal places. Negative values are allowed down to −273.15 °C or −459.67 °F (absolute zero). The calculator converts readings, not temperature changes: a change of 1 °C is a change of 1.8 °F, with no 32-degree offset. NIST temperature conversion reference.
Changing the input updates the calculator only; the worked example below it stays on the value named in this page. Swap uses the displayed, rounded result as the next input, so repeated swaps may introduce a small rounding difference. Unit conversion does not determine a diagnosis or a recommended device setting.
