How to Convert ppm per °F) to ppm per Kelvin)
To convert ppm per °f) to ppm per kelvin), multiply the thermal expansion by the following conversion ratio: 1.8 ppm per kelvin)/microinch per inch-°f.
Since one microinch per inch-°f is equal to 1.8 ppm per kelvin), you can use this simple formula to convert:
The thermal expansion in ppm per kelvin) is equal to the thermal expansion in ppm per °f) multiplied by 1.8.
For example, here's how to convert 5 ppm per °f) to ppm per kelvin) using the formula above.
How Many ppm per Kelvin) Are in a Microinch per Inch-°F?
There are 1.8 ppm per kelvin) in a microinch per inch-°f, which is why we use this value in the formula above.
Our microinch per inch-°f to micrometer per meter-kelvin calculator automatically converts your thermal expansion measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
ppm per °F) and ppm per kelvin) are both units used to measure thermal expansion. Keep reading to learn more about each unit.
What Is a Microinch per Inch-°F?
A microinch per inch-°f is a unit of thermal expansion equal to 0.0000018 per kelvin (1/K), the base unit for thermal expansion. US engineering expansion unit (1.8×10⁻⁶ /K). [1]
The microinch per inch-°f is classified as a US customary unit of thermal expansion. ppm per °F) can be abbreviated as ppm/°F; for example, 1 microinch per inch-°f can be written as 1 ppm/°F.
In the metric system, "micro" is the standard SI prefix for millionths, or 10⁻⁶. This makes the microinch per inch-°f (ppm/°F) a convenient decimal multiple of the length/length per kelvin (1/K).
In practice, ppm per °f) (ppm/°F) are widely used across fine-tolerance laboratory, analytical, and micro-scale thermal expansion measurements within US customary workflows, engineering documentation, and technical data sheets.
What Is a Micrometer per Meter-Kelvin?
A micrometer per meter-kelvin is a unit of thermal expansion equal to 1/1,000,000 of a length/length per kelvin (0.000001 1/K). Engineering thermal expansion unit (10⁻⁶ /K). [2]
The micrometer per meter-kelvin is classified as a metric and SI-compatible unit of thermal expansion. ppm per Kelvin) can be abbreviated as ppm/K; for example, 1 micrometer per meter-kelvin can be written as 1 ppm/K.
In the metric system, "micro" is the standard SI prefix for millionths, or 10⁻⁶. This makes the micrometer per meter-kelvin (ppm/K) a convenient decimal multiple of the length/length per kelvin (1/K).
In practice, ppm per kelvin) (ppm/K) are widely used across fine-tolerance laboratory, analytical, and micro-scale thermal expansion measurements within SI metric workflows, engineering documentation, and technical data sheets.
When converting thermal expansion between ppm per °f) (ppm/°F) and ppm per kelvin) (ppm/K), keep full floating-point precision (1 ppm/°F = 1.8 ppm/K; 1 ppm/K = 0.5555556 ppm/°F) during intermediate calculations and round only the final micrometer per meter-kelvin figure to match your instrument tolerance.
