How to Calculate Celsius to Fahrenheit

What is Celsius to Fahrenheit?

Temperature conversion between Celsius and Fahrenheit. Formula: °F = (°C × 9/5) + 32. Reverse: °C = (°F − 32) × 5/9. Key reference: 0°C = 32°F, 100°C = 212°F, 37°C = 98.6°F, −40°C = −40°F.

Formula

°F = (°C × 9/5) + 32
F
(°C × 9/5) + 32 — (°C × 9/5) + 32
C
(°F − 32) × 5/9 — (°F − 32) × 5/9

Step-by-Step Guide

  1. 1°F = (°C × 9/5) + 32
  2. 2°C = (°F − 32) × 5/9
  3. 3Quick estimate: subtract 30 then halve (±3° accuracy)
