Per Fahrenheit compared with ppm per °F

One 1/°F is 1,000,000 times as large as one ppm/°F, so your number gets bigger when you convert Per Fahrenheit to ppm per °F and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.

About Per Fahrenheit and ppm per °F

Per degree Fahrenheit (1/°F): Per Fahrenheit degree; as a unit it equals 1.8 per kelvin, so a material’s per-°F value is 5/9 of its per-kelvin value. Parts per million per °F (ppm/°F): Parts per million per Fahrenheit degree; as a unit it equals 1.8×10⁻⁶ per kelvin.

How to calculate Per Fahrenheit to ppm per °F step by step

  1. Enter the value in 1/°F (the starting unit).
  2. Multiply by 1,000,000, because 1 1/°F = 1,000,000 ppm/°F.
  3. The product is the value in ppm/°F. To go back, divide by 1,000,000 or multiply by 0.000001.
