Per Kelvin to ppm per °C formula and what each symbol means
ppm/°C = 1/K × 1,000,000
| Symbol | Meaning |
|---|---|
| 1/K | Per kelvin |
| ppm/°C | Parts per million per °C |
Per Kelvin to ppm per °C examples
1 1/K
1 1/K × 1,000,000 = 1,000,000 ppm/°C.
10 1/K
10 1/K × 1,000,000 = 10,000,000 ppm/°C.
100 1/K
100 1/K × 1,000,000 = 100,000,000 ppm/°C.
Per Kelvin compared with ppm per °C
One 1/K is 1,000,000 times as large as one ppm/°C, so your number gets bigger when you convert Per Kelvin to ppm per °C and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.
About Per Kelvin and ppm per °C
Per kelvin (1/K): Per kelvin, the SI unit of a thermal expansion coefficient. Parts per million per °C (ppm/°C): Parts per million per Celsius degree, 1×10⁻⁶ per kelvin.
How to calculate Per Kelvin to ppm per °C step by step
- Enter the value in 1/K (the starting unit).
- Multiply by 1,000,000, because 1 1/K = 1,000,000 ppm/°C.
- The product is the value in ppm/°C. To go back, divide by 1,000,000 or multiply by 0.000001.
