Convert thermal expansion coefficient units including per kelvin, per celsius, per fahrenheit, microstrain per celsius, microstrain per fahrenheit, parts per million per kelvin, and more.
Per kelvin to ppm/K:
1 1/K = 1,000,000 ppm/K
ppm/K to per kelvin:
1 ppm/K = 0.000001 1/K
Per celsius to per fahrenheit:
1 1/°C = 0.555556 1/°F
Microstrain per celsius to ppm/K:
1 µε/°C = 1 ppm/K
Thermal expansion conversions are useful for material data sheets, structural movement, pipe expansion, mechanical fits, bridges, rails, concrete slabs, glass panels, electronics, and temperature-based design checks.
Use this converter when comparing SI, U.S. customary, ppm, and microstrain-based thermal expansion coefficient units.
Your result shows the entered thermal expansion coefficient converted from the starting unit into the selected ending unit. The calculator also shows the conversion rate used so you can verify the calculation.
For engineering and material design, make sure the coefficient unit matches your formula, material data sheet, temperature scale, or design reference.
Thermal expansion coefficient measures how much a material changes length, area, or volume per degree of temperature change.
The common SI unit for coefficient of thermal expansion is per kelvin, written as 1/K.
Yes. For linear expansion, 1 ppm/K equals 1 microstrain per kelvin.
For temperature differences, 1/K and 1/°C are numerically equivalent.
This converter is designed for expansion coefficient magnitude conversions, so it uses non-negative values.
