Per kelvin to ppm per kelvin
Type a value in 1/K to get it in ppm/K instantly.
12,000,000ppm/K
That's 171,429× as much as plastic — nothing on our list beats it. A 10 m beam would move about 4,800,000 mm over a 40 °C swing.
Convert the other way: ppm/K to 1/K
What it means
How much does it move?
Linear expansion. Volume expansion is roughly three times the linear figure for solids.
The math
How to convert 1/K to ppm/K
To convert per kelvin to ppm per kelvin, multiply by 1,000,000.
Example: 12 1/K × 1,000,000 = 12,000,000 ppm/K.
In the other direction, 1 ppm/K = 1×10⁻⁶ 1/K.

The units
About these units
Per kelvin (1/K)
The raw SI form. Steel is 0.000012 per kelvin, which is why ppm is preferred.
Ppm per kelvin (ppm/K)
Parts per million per kelvin, the everyday engineering unit. Steel is 12.
