Thermal expansion converter
How much a material grows per degree. 6 units, converted from one table of exact factors.
—
1 1/kelvin in every other thermal expansion unit
Computed by the same engine that runs the converter above, so these can never drift apart from it.
| From | Equals | Unit |
|---|---|---|
| 1 1/kelvin | 1 | 1/degree Celsius (1/°C) |
| 1 1/kelvin | 0.5555555556 | 1/degree Fahrenheit (1/°F) |
| 1 1/kelvin | 0.5555555556 | 1/degree Rankine (1/°R) |
| 1 1/kelvin | 1,000,000 | ppm/kelvin (ppm/K) |
| 1 1/kelvin | 1,000,000 | micrometer/meter·kelvin (µm/m·K) |
What each unit actually is
Most converters give you a number and stop. Where a figure is exact by definition we say so, and where it is an average or shifts with conditions we say that too — that is usually the thing you needed to know.
| Unit | Symbol | What it actually is |
|---|---|---|
| 1/kelvin | 1/K | SI. |
| 1/degree Celsius | 1/°C | Identical — the degrees are the same size. |
| 1/degree Fahrenheit | 1/°F | |
| 1/degree Rankine | 1/°R | |
| ppm/kelvin | ppm/K | The form data sheets usually print. |
| micrometer/meter·kelvin | µm/m·K | The same number as ppm/K. |
