ppm per °F to Per Fahrenheit formula and what each symbol means
1/°F = ppm/°F × 0.000001
| Symbol | Meaning |
|---|---|
| ppm/°F | Parts per million per °F |
| 1/°F | Per degree Fahrenheit |
ppm per °F to Per Fahrenheit examples
1 ppm/°F
1 ppm/°F × 0.000001 = 0.000001 1/°F.
10 ppm/°F
10 ppm/°F × 0.000001 = 0.00001 1/°F.
100 ppm/°F
100 ppm/°F × 0.000001 = 0.0001 1/°F.
ppm per °F compared with Per Fahrenheit
One 1/°F is 1,000,000 times as large as one ppm/°F, so your number gets smaller when you convert ppm per °F 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 °F and Per Fahrenheit
Parts per million per °F (ppm/°F): Parts per million per Fahrenheit degree; as a unit it equals 1.8×10⁻⁶ 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 °F to Per Fahrenheit step by step
- Enter the value in ppm/°F (the starting unit).
- Multiply by 0.000001, because 1 ppm/°F = 0.000001 1/°F.
- The product is the value in 1/°F. To go back, divide by 0.000001 or multiply by 1,000,000.

- Forgetting that ppm means ×10⁻⁶.
- Dividing when you should multiply: from ppm/°F to 1/°F multiply by 0.000001; from 1/°F to ppm/°F divide by 0.000001.
ppm per °F to Per Fahrenheit FAQ
How many 1/°F are in 1 ppm/°F?
1 ppm/°F equals 0.000001 1/°F.
How many ppm/°F are in 1 1/°F?
1 1/°F equals 1,000,000 ppm/°F.
Is 1 ppm/°F = 0.000001 1/°F an exact conversion?
The factor is shown rounded to 7 significant figures (0.000001). The calculator above uses more digits.
What is a 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 can I estimate ppm per °F to Per Fahrenheit in my head?
One 1/°F is 1,000,000 times as large as one ppm/°F, so your number gets smaller when you convert ppm per °F to Per Fahrenheit and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.
What is 0.5 ppm/°F in Per Fahrenheit?
0.5 ppm/°F = 5×10⁻⁷ 1/°F (since 0.5 × 0.000001).
What is 25 ppm/°F in Per Fahrenheit?
25 ppm/°F = 0.000025 1/°F (since 25 × 0.000001).
What is 80 ppm/°F in Per Fahrenheit?
80 ppm/°F = 0.00008 1/°F (since 80 × 0.000001).
How many decimals should I keep when converting ppm/°F to 1/°F?
Match the precision of your original measurement. For example, 0.00001 1/°F rounds to 0.00001 1/°F at 3 significant figures; keep more digits only for engineering or scientific work.
