Formula and unit definitions

Convert linear or volumetric thermal expansion coefficients per temperature interval; compare like quantities only.

target value = source value × source factor ÷ target factor

Source unit: parts per million per kelvin (ppm-K), factor 1e-06, offset 0.

Target unit: per degree Fahrenheit (1-F), factor 1.8, offset 0.

Important note

The calculation is performed locally from the listed unit definitions. Display results are rounded for readability; high-precision and regulated work should use the governing standard and appropriate significant figures.

For high-precision, regulated or safety-critical use, check the underlying standard and its required precision. Historical and approximate units are identified in their names or family descriptions.
