Frequently asked

What is the formula for converting Fahrenheit (oven) to Celsius (oven)?+
The formula is: 1 °F = -17.2222 °C. Type any value into the calculator above and the result appears instantly.
How do I convert Celsius (oven) back to Fahrenheit (oven)?+
Click the swap button (⇄) above to go to the Celsius (oven) → Fahrenheit (oven) converter, or use the inverse formula derived from the one shown.
How accurate is the conversion?+
Conversion factors used here are exact rational values from NIST SP 811 and the BIPM SI brochure (e.g. 1 ft = 0.3048 m exactly, 1 lb = 0.45359237 kg exactly). Trailing-digit differences vs hand calculation come only from binary floating-point representation, never from the conversion factor itself.
Where do these conversion factors come from?+
Length and mass factors come from the 1959 international yard-and-pound agreement; SI base units (metre, kilogram, second, kelvin) come from the 2019 BIPM redefinition; energy and pressure factors are NIST SP 811 reference values. Each editorial section above lists the specific source for that category.
Can I copy the conversion factor for use elsewhere?+
Yes. The factor in the formula above is the exact rational value used internally; copying it into Excel or another tool reproduces the result to floating-point precision.
