ppm per °C to Per Fahrenheit examples
1 ppm/°C
1 ppm/°C × 5.555556×10⁻⁷ = 5.555556×10⁻⁷ 1/°F.
10 ppm/°C
10 ppm/°C × 5.555556×10⁻⁷ = 0.000005555556 1/°F.
100 ppm/°C
100 ppm/°C × 5.555556×10⁻⁷ = 0.00005555556 1/°F.
ppm per °C compared with Per Fahrenheit
One 1/°F is 1,800,000 times as large as one ppm/°C, so your number gets smaller when you convert ppm per °C to Per Fahrenheit and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.
About ppm per °C and Per Fahrenheit
Parts per million per °C (ppm/°C): Parts per million per Celsius degree, 1×10⁻⁶ per kelvin. 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.
How to calculate ppm per °C to Per Fahrenheit step by step
- Enter the value in ppm/°C (the starting unit).
- Multiply by 5.555556×10⁻⁷, because 1 ppm/°C = 5.555556×10⁻⁷ 1/°F.
- The product is the value in 1/°F. To go back, divide by 5.555556×10⁻⁷ or multiply by 1,800,000.
