300°F to Celsius

148.9°C

300°F = 148.9°C = 422.04 K

Working: (300 − 32) × 5/9 = 148.9

300 degrees Fahrenheit converts to 148.9 degrees Celsius.

To convert Fahrenheit to Celsius, subtract 32 first, then multiply by 5/9. For 300°F: 300 − 32 = 268, and 268 × 5/9 = 148.9. The subtraction comes first because the two scales have different zero points — water freezes at 0°C but at 32°F.

A quick mental estimate is to subtract 30 and halve the result, which gives about 135°C — 13.9 degrees off the exact 148.9°C. That is close enough to judge the weather, though it drifts badly at oven temperatures.

Three hundred degrees is a slow oven, used for long braises and for holding food without cooking it further. It converts to 148.9°C, which European recipes would round to 150 — the two oven ladders run on different increments, so converted temperatures rarely land on a mark the dial actually has.

Frequently asked questions

What is 300 degrees Fahrenheit in Celsius?

300°F is 148.9°C. Subtract 32 from 300 to get 268, then multiply by 5/9 to get 148.9.

What is the formula for Fahrenheit to Celsius?

°C = (°F − 32) × 5/9. Subtract 32 from the Fahrenheit temperature, then multiply the result by 5/9 (about 0.5556).
