-15.56 °C

Formula and Step-by-Step

°C = (°F - 32) × 5/9

Start with 4°F
Subtract 32: 4 - 32 = -28
Multiply by 5/9: -28 × 0.5556 = -15.56
Result: 4°F = -15.56°C

Quick Mental Conversion

For a rough estimate, subtract 30 then halve. For example, 4 °F: minus 30 is -26, halved is -13. The exact answer is -15.56 °C.
