How to Convert BTUs per Hour-Sq. Foot-°F to Kilowatts per Square Meter-Kelvin
To convert btus per hour-sq. foot-°f to kilowatts per square meter-kelvin, multiply the heat transfer coefficient by the following conversion ratio: 0.0056783 kilowatts per square meter-kelvin/btu per hour-sq. foot-°f.
Since one btu per hour-sq. foot-°f is equal to 0.0056783 kilowatts per square meter-kelvin, you can use this simple formula to convert:
The heat transfer coefficient in kilowatts per square meter-kelvin is equal to the heat transfer coefficient in btus per hour-sq. foot-°f multiplied by 0.0056783.
For example, here's how to convert 5 btus per hour-sq. foot-°f to kilowatts per square meter-kelvin using the formula above.
How Many Kilowatts per Square Meter-Kelvin Are in a BTU per Hour-Sq. Foot-°F?
There are 0.0056783 kilowatts per square meter-kelvin in a btu per hour-sq. foot-°f, which is why we use this value in the formula above.
Our btu per hour-sq. foot-°f to kilowatt per square meter-kelvin calculator automatically converts your heat transfer coefficient measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
BTUs per Hour-Sq. Foot-°F and kilowatts per square meter-kelvin are both units used to measure heat transfer coefficient. Keep reading to learn more about each unit.
What Is a BTU per Hour-Sq. Foot-°F?
A btu per hour-sq. foot-°f is a unit of heat transfer coefficient equal to 5.6782633 watts per square meter-kelvin (W/(m²·K)), the base unit for heat transfer coefficient. US fenestration U-factor and heat exchanger coefficient (≈ 5.6783 W/(m²·K)). [1]
The btu per hour-sq. foot-°f is classified as a US customary unit of heat transfer coefficient. BTUs per Hour-Sq. Foot-°F can be abbreviated as BTU/(h·ft²·°F); for example, 1 btu per hour-sq. foot-°f can be written as 1 BTU/(h·ft²·°F).
When working with btus per hour-sq. foot-°f (BTU/(h·ft²·°F)) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, btus per hour-sq. foot-°f (BTU/(h·ft²·°F)) are widely used across standard heat transfer coefficient applications within US customary workflows, engineering documentation, and technical data sheets.
What Is a Kilowatt per Square Meter-Kelvin?
A kilowatt per square meter-kelvin is a unit of heat transfer coefficient equal to 1,000 watts per square meter-kelvin (W/(m²·K)), the base unit for heat transfer coefficient. Equal to 1,000 W/(m²·K). [2]
The kilowatt per square meter-kelvin is classified as a metric and SI-compatible unit of heat transfer coefficient. Kilowatts per Square Meter-Kelvin can be abbreviated as kW/(m²·K); for example, 1 kilowatt per square meter-kelvin can be written as 1 kW/(m²·K).
In the metric system, "kilo" is the standard SI prefix for thousands, or 10³. This makes the kilowatt per square meter-kelvin (kW/(m²·K)) a convenient decimal multiple of the watt per square meter-kelvin (W/(m²·K)).
In practice, kilowatts per square meter-kelvin (kW/(m²·K)) are widely used across large-scale industrial, bulk, and macro-level heat transfer coefficient specifications within SI metric workflows, engineering documentation, and technical data sheets.
When converting heat transfer coefficient between btus per hour-sq. foot-°f (BTU/(h·ft²·°F)) and kilowatts per square meter-kelvin (kW/(m²·K)), keep full floating-point precision (1 BTU/(h·ft²·°F) = 0.0056783 kW/(m²·K); 1 kW/(m²·K) = 176.1101837 BTU/(h·ft²·°F)) during intermediate calculations and round only the final kilowatt per square meter-kelvin figure to match your instrument tolerance.
