18 Fahrenheit to Kelvin

18 fahrenheit equals 265.37 kelvin. Use the formula, worked example, and conversion table below to check the math.

18 °F = 265.37 K
K = (°F - 32) × 5/9 + 273.15
Try: 13 °F to K 17 °F to K 19 °F to K 23 °F to K
18 °F is also
18 °F = -7.78 °C
°F
265.37 K

Formula and Step-by-Step

K = (°F - 32) × 5/9 + 273.15
  1. Start with 18°F
  2. Convert to Celsius: (18 - 32) × 5/9 = -7.78°C
  3. Add 273.15: -7.78 + 273.15 = 265.37
  4. Result: 18°F = 265.37 K

18 °F on the Temperature Scale

18 °F = 265.37 K
Freezing (0°C)
Body temp (37°C)
Boiling (100°C)

18 °F equals 265.37 K on the temperature scale.
