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

  1. Enter the value in 1/K (the starting unit).
  2. Multiply by 1,000,000, because 1 1/K = 1,000,000 ppm/°C.
  3. The product is the value in ppm/°C. To go back, divide by 1,000,000 or multiply by 0.000001.
