How do you convert degrees celsius per watt to kelvins per watt?

To convert degrees celsius per watt (°C/W) to kelvins per watt (K/W), multiply the measurement in degrees celsius per watt by 1 (kelvins per watt = degrees celsius per watt × 1).

What is 10 degrees celsius per watt in kelvins per watt?

10 degrees celsius per watt (10 °C/W) is equal to 10 kelvins per watt (10 K/W).

Which is larger, 1 degree celsius per watt (°C/W) or 1 kelvin per watt (K/W)?

One degree celsius per watt (°C/W) is larger than one kelvin per watt (K/W). Specifically, 1 °C/W contains 1 K/W, whereas 1 K/W is 1 °C/W.

How do I convert back from kelvins per watt (K/W) to degrees celsius per watt (°C/W)?

To reverse the calculation from K/W to °C/W, multiply your kelvin per watt value by the inverse factor 1 (or divide by 1). You can also click the Swap button in the tool above to flip directions in one click.

How many decimal places should I round °C/W to K/W results to?

For everyday comparisons and quick estimates, rounding to 2 decimal places is usually sufficient (for example, 10 °C/W ≈ 10.00 K/W). For engineering, laboratory, or machining specifications, select 4 or 6 decimals—or Scientific (10ⁿ) mode—in the calculator toolbar above.

How to Convert Degrees Celsius per Watt to Kelvins per Watt

To convert degrees celsius per watt to kelvins per watt, multiply the thermal resistance by the following conversion ratio: 1 kelvins per watt/degree celsius per watt.

Since one degree celsius per watt is equal to 1 kelvins per watt, you can use this simple formula to convert:

kelvins per watt = degrees celsius per watt × 1

The thermal resistance in kelvins per watt is equal to the thermal resistance in degrees celsius per watt multiplied by 1.

For example, here's how to convert 10 degrees celsius per watt to kelvins per watt using the formula above.

kelvins per watt = (10 °C/W × 1) = 10 K/W

How Many Kelvins per Watt Are in a Degree Celsius per Watt?

There are 1 kelvins per watt in a degree celsius per watt, which is why we use this value in the formula above.

1 °C/W = 1 K/W|1 K/W = 1 °C/W

Our degree celsius per watt to kelvin per watt calculator automatically converts your thermal resistance measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

Degrees Celsius per Watt and kelvins per watt are both units used to measure thermal resistance. Keep reading to learn more about each unit.

What Is a Degree Celsius per Watt?

A degree celsius per watt is a unit of thermal resistance equal to 1 kelvins per watt (K/W), the base unit for thermal resistance. Electronics heatsink thermal resistance unit (1 °C/W = 1 K/W). [1]

The degree celsius per watt is classified as a metric and SI-compatible unit of thermal resistance. Degrees Celsius per Watt can be abbreviated as °C/W; for example, 1 degree celsius per watt can be written as 1 °C/W.

When working with degrees celsius per watt (°C/W) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.

In practice, degrees celsius per watt (°C/W) are widely used across standard thermal resistance applications within SI metric workflows, engineering documentation, and technical data sheets.

What Is a Kelvin per Watt?

SI unit of absolute thermal resistance. It serves as a primary reference unit for measuring thermal resistance across scientific and practical applications. [2]

The kelvin per watt is classified as an International System of Units (SI) unit of thermal resistance. Kelvins per Watt can be abbreviated as K/W; for example, 1 kelvin per watt can be written as 1 K/W.

As the primary coherent reference unit for thermal resistance in this category, all other thermal resistance units are mathematically anchored to the kelvin per watt (K/W).

In practice, kelvins per watt (K/W) are widely used across standard thermal resistance applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.

Learn more about kelvins per watt in our Thermal Resistance Converter.

When converting thermal resistance between degrees celsius per watt (°C/W) and kelvins per watt (K/W), keep full floating-point precision (1 °C/W = 1 K/W; 1 K/W = 1 °C/W) during intermediate calculations and round only the final kelvin per watt figure to match your instrument tolerance.
