Step-by-Step Calculation

°C = (°F - 32) × 5/9
  1. Start with 172°F
  2. Subtract 32: 172 - 32 = 140
  3. Multiply by 5/9: 140 × 0.5556 = 77.78
  4. Result: 172°F = 77.78°C

Quick Mental Conversion

For a rough estimate, subtract 30 then halve. For example, 172 °F: minus 30 is 142, halved is 71. The exact answer is 77.78 °C.
