ppm per °C to Per Kelvin formula and what each symbol means
1/K = ppm/°C × 0.000001
| Symbol | Meaning |
|---|---|
| ppm/°C | Parts per million per °C |
| 1/K | Per kelvin |
ppm per °C to Per Kelvin examples
1 ppm/°C
1 ppm/°C × 0.000001 = 0.000001 1/K.
10 ppm/°C
10 ppm/°C × 0.000001 = 0.00001 1/K.
100 ppm/°C
100 ppm/°C × 0.000001 = 0.0001 1/K.
ppm per °C compared with Per Kelvin
One 1/K is 1,000,000 times as large as one ppm/°C, so your number gets smaller when you convert ppm per °C to Per Kelvin 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 Kelvin
Parts per million per °C (ppm/°C): Parts per million per Celsius degree, 1×10⁻⁶ per kelvin. Per kelvin (1/K): Per kelvin, the SI unit of a thermal expansion coefficient.
How to calculate ppm per °C to Per Kelvin step by step
- Enter the value in ppm/°C (the starting unit).
- Multiply by 0.000001, because 1 ppm/°C = 0.000001 1/K.
- The product is the value in 1/K. To go back, divide by 0.000001 or multiply by 1,000,000.

Common mistakes when calculating ppm per °C to Per Kelvin
- Forgetting that ppm means ×10⁻⁶.
- Dividing when you should multiply: from ppm/°C to 1/K multiply by 0.000001; from 1/K to ppm/°C divide by 0.000001.
ppm per °C to Per Kelvin FAQ
How many 1/K are in 1 ppm/°C?
1 ppm/°C equals 0.000001 1/K.
How many ppm/°C are in 1 1/K?
1 1/K equals 1,000,000 ppm/°C.
Is 1 ppm/°C = 0.000001 1/K an exact conversion?
The factor is shown rounded to 7 significant figures (0.000001). The calculator above uses more digits.
What is a parts per million per °C (ppm/°C)?
Parts per million per Celsius degree, 1×10⁻⁶ per kelvin.
How can I estimate ppm per °C to Per Kelvin in my head?
One 1/K is 1,000,000 times as large as one ppm/°C, so your number gets smaller when you convert ppm per °C to Per Kelvin and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.
What is 25 ppm/°C in Per Kelvin?
25 ppm/°C = 0.000025 1/K (since 25 × 0.000001).
What is 80 ppm/°C in Per Kelvin?
80 ppm/°C = 0.00008 1/K (since 80 × 0.000001).
What is 500 ppm/°C in Per Kelvin?
500 ppm/°C = 0.0005 1/K (since 500 × 0.000001).
How many decimals should I keep when converting ppm/°C to 1/K?
Match the precision of your original measurement. For example, 0.00001 1/K rounds to 0.00001 1/K at 3 significant figures; keep more digits only for engineering or scientific work.
