Temperature Converter
Craft instructions come from everywhere, so oven temperatures arrive in Celsius from Europe and Fahrenheit from the United States, and kiln and wax figures sometimes appear in Kelvin. This converter handles all three and shows the working temperatures a maker actually looks up, from chocolate tempering to home oven settings.
Convert a measurement
Enter your own figure, pick the units on each side, and the result is worked out as you go. Nothing is stored.
All units at once
The same quantity written every way this page knows, so you do not have to convert twice.
Nothing entered yet, so the table below uses Celsius (°C) as an example.
| Unit | Value |
|---|---|
| Celsius (°C) Starting value | 1 |
| Fahrenheit (°F) | 33.8 |
| Kelvin (K) | 274.15 |
What this assumes
- Temperature does not convert by a simple ratio, so this page uses the proper formulas: F = C x 9/5 + 32, C = (F - 32) x 5/9, K = C + 273.15.
- Home oven thermostats are typically accurate to about plus or minus 10 degrees Celsius, so a stated oven temperature is a target rather than a guarantee. An oven thermometer is the only way to know your own oven.
- This page converts temperatures only. It gives no firing, melting or curing schedules: follow the manufacturer data for your material and kiln.
Every figure on this page is worked out from celsius, and the page states the factor rather than hiding it.
Questions people ask
How do I convert Celsius to Fahrenheit?
Multiply by 9, divide by 5, then add 32. So 180 degrees Celsius is 180 x 9 / 5 + 32, which is 356 degrees Fahrenheit. A quick mental approximation is to double the Celsius figure and add 30, which is close enough for a rough oven setting.
What is 350 Fahrenheit in Celsius?
About 177 degrees Celsius, usually rounded to 180 in recipes written in Celsius. That difference is inside the tolerance of most ovens, so either setting works.
What is the difference between Celsius and Kelvin?
They use the same degree size, but Kelvin starts at absolute zero. To go from Celsius to Kelvin, add 273.15. So 20 degrees Celsius is 293.15 Kelvin. Craft work uses Kelvin mainly in colour temperature and in some industrial material data.
Is there a temperature where Celsius and Fahrenheit are the same?
Yes, at minus 40 degrees. It is the one point where the two scales agree, which makes it a handy check that a conversion formula is written correctly.
