-0.5556 °C

Formula and Step-by-Step

°C = (°F - 32) × 5/9

Start with 31°F
Subtract 32: 31 - 32 = -1
Multiply by 5/9: -1 × 0.5556 = -0.5556
Result: 31°F = -0.5556°C

Quick Mental Conversion

For a rough estimate, subtract 30 then halve. For example, 31 °F: minus 30 is 1, halved is 0.5. The exact answer is -0.5556 °C.
