Conversion Formula

°C = (°F − 32) × 5/9
Equivalently: °C = (°F − 32) ÷ 1.8

Key reference points:
   32°F =   0°C  (water freezes)
   68°F =  20°C  (comfortable room temperature)
   98.6°F = 37°C (normal body temperature)
  100.4°F = 38°C (fever threshold)
  212°F = 100°C  (water boils at sea level)

US weather context:
   0°F = −17.8°C  very cold winter
  32°F =   0.0°C  freezing
  68°F =  20.0°C  comfortable room temp
 100°F =  37.8°C  extreme heat / high fever

Oven temperatures:
  325°F = 162.8°C  moderate-low
  350°F = 176.7°C  most common baking temp
  400°F = 204.4°C  hot oven
  450°F = 232.2°C  very hot

Frequently Asked Questions

What is 70°F in Celsius?

70°F equals approximately 21.1°C. The calculation: (70 − 32) × 5/9 = 38 × 5/9 = 21.1°C. 70°F is a typical comfortable indoor temperature in the US.

What is 350°F in Celsius?

350°F equals approximately 176.7°C. This is a very common oven temperature for baking cookies, cakes, and many other items. It is also sometimes given as Gas Mark 4 in older UK and European oven guides.

What is the quick estimate formula for F to C?

A quick mental estimate: subtract 32, then divide by 2 (instead of 1.8). This gives a result within about 10% of the exact value. Example: 68°F → (68 − 32) ÷ 2 = 18°C (exact is 20°C). More accurate quick method: subtract 32, then multiply by 0.55.

What is 98.6°F in Celsius?

(98.6 − 32) × 5/9 = 66.6 × 5/9 = 37°C — normal human body temperature. A temperature of 100.4°F (38°C) or above is generally considered a fever in adults.

What is 0°F in Celsius?

(0 − 32) × 5/9 = −32 × 5/9 = −17.8°C. This is extremely cold winter weather — dangerous exposure risk for unprotected skin.
