How to convert ppm per kelvin to per kelvin
1/K = ppm/K × 0.000001Multiply the value in ppm per kelvin by 0.000001. To go the other way, multiply by 1,000,000 (or divide by 0.000001).
A part per million per kelvin is smaller than a per kelvin: it takes 1,000,000 ppm per kelvin to make one per kelvin.
Worked examples
- 1 part per million per kelvin1 ppm/K × 0.000001 = 0.000001 1/K
- 5 ppm per kelvin5 ppm/K × 0.000001 = 0.000005 1/K
- 10 ppm per kelvin10 ppm/K × 0.000001 = 0.00001 1/K
- 20 ppm per kelvin20 ppm/K × 0.000001 = 0.00002 1/K
- 100 ppm per kelvin100 ppm/K × 0.000001 = 0.0001 1/K

About the units
Part per million per kelvin (ppm/K)
The part per million per kelvin (ppm/K) is a unit of thermal expansion. One part per million per kelvin equals 0.000001 per kelvin (1/K).
Per kelvin (1/K)
The per kelvin (1/K) is a unit of thermal expansion in the International System of Units (SI).
Frequently asked questions
How many per kelvin are in one part per million per kelvin?
There are 0.000001 per kelvin in one part per million per kelvin, and this value is exact by definition.
How do I convert ppm per kelvin to per kelvin?
Multiply the number of ppm per kelvin by 0.000001. For example, 10 ppm/K × 0.000001 = 0.00001 1/K.
How many ppm per kelvin are in one per kelvin?
One per kelvin equals 1,000,000 ppm per kelvin. That is the reverse factor, 1 ÷ 0.000001.
What is 10 ppm per kelvin in per kelvin?
10 ppm/K = 0.00001 1/K.
Is this ppm/K to 1/K converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
