Kelvin per watt compared with °F·h per Btu
One °F·h/Btu is 1.896 times as large as one K/W, so your number gets smaller when you convert kelvin per watt to °F·h per Btu and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.
About kelvin per watt and °F·h per Btu
Kelvin per watt (K/W): Kelvin per watt, the SI unit of thermal resistance. Degree Fahrenheit hour per Btu (°F·h/Btu): Fahrenheit-degree hours per British thermal unit, about 1.8956 K/W.
How to calculate Kelvin per watt to °F·h per Btu step by step
- Enter the value in K/W (the starting unit).
- Multiply by 0.5275279, because 1 K/W = 0.5275279 °F·h/Btu.
- The product is the value in °F·h/Btu. To go back, divide by 0.5275279 or multiply by 1.895634.
