Full temperature conversion chart
Celsius, Fahrenheit and Kelvin side by side. These are the same tables as the printable PDF. For: Students, scientists, engineers and cooks.
- Exact definition
- K = °C + 273.15 and °F = °C × 9/5 + 32 (exact)
- Formula
- °F = (°C × 1.8) + 32; K = °C + 273.15
- Reverse
- °C = (°F − 32) ÷ 1.8; °C = K − 273.15
- Worked example
- 25 °C = 77 °F = 298.15 K
- Rounding
- Values are rounded to 2 decimal places.
