How to Convert BTU/hr to Terawatts
To convert btu/hr to terawatts, multiply the power by the following conversion ratio: 2.930711e-13 terawatts/btu per hour.
Since one btu per hour is equal to 2.930711e-13 terawatts, you can use this simple formula to convert:
The power in terawatts is equal to the power in btu/hr multiplied by 2.930711e-13.
For example, here's how to convert 5 btu/hr to terawatts using the formula above.
How Many Terawatts Are in a BTU per Hour?
There are 2.930711e-13 terawatts in a btu per hour, which is why we use this value in the formula above.
Our btu per hour to terawatt calculator automatically converts your power measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
BTU/hr and terawatts are both units used to measure power. Keep reading to learn more about each unit.
What Is a BTU per Hour?
A btu per hour is a unit of power equal to 0.2930711 watts (W), the base unit for power. HVAC thermal rate (1 W ≈ 3.41214 BTU/hr). [1]
The btu per hour is classified as a US customary and imperial unit of power. BTU/hr can be abbreviated as BTU/hr; for example, 1 btu per hour can be written as 1 BTU/hr.
When working with btu/hr (BTU/hr) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, btu/hr (BTU/hr) are widely used across standard power applications within US customary and imperial workflows, engineering documentation, and technical data sheets.
What Is a Terawatt?
A terawatt is a unit of power equal to 1e+12 watts (W), the base unit for power. Equal to 10¹² Watts (1,000 GW). [2]
The terawatt is classified as an International System of Units (SI) unit of power. Terawatts can be abbreviated as TW; for example, 1 terawatt can be written as 1 TW.
In the metric system, "tera" is the standard SI prefix for trillions, or 10¹². This makes the terawatt (TW) a convenient decimal multiple of the watt (W).
In practice, terawatts (TW) are widely used across large-scale industrial, bulk, and macro-level power specifications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
When converting power between btu/hr (BTU/hr) and terawatts (TW), keep full floating-point precision (1 BTU/hr = 2.930711e-13 TW; 1 TW = 3.412142e+12 BTU/hr) during intermediate calculations and round only the final terawatt figure to match your instrument tolerance.
