Calculation for 27 °C
(27 × 9/5) + 32 = 48.6 + 32 = 80.6 °F.
For this input, 80.6 °F 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.
