-17.22 °C

Formula and Step-by-Step

°C = (°F - 32) × 5/9

Start with 1°F
Subtract 32: 1 - 32 = -31
Multiply by 5/9: -31 × 0.5556 = -17.22
Result: 1°F = -17.22°C

Quick Mental Conversion

For a rough estimate, subtract 30 then halve. For example, 1 °F: minus 30 is -29, halved is -14.5. The exact answer is -17.22 °C.
