172.78 °C

Formula and Step-by-Step

°C = (°F - 32) × 5/9
  1. Start with 343°F
  2. Subtract 32: 343 - 32 = 311
  3. Multiply by 5/9: 311 × 0.5556 = 172.78
  4. Result: 343°F = 172.78°C

Quick Mental Conversion

For a rough estimate, subtract 30 then halve. For example, 343 °F: minus 30 is 313, halved is 156.5. The exact answer is 172.78 °C.
