Type the Fahrenheit value and read the Celsius result instantly.
How It Works
The formula is: C = (F - 32) x 5/9. For example, 72 degrees F = (72 - 32) x 5/9 = 22.2 degrees C. Quick mental math: subtract 30 and divide by 2 for a rough estimate (72 - 30 = 42, 42 / 2 = 21 — close to the actual 22.2).
