How to Convert Terawatt to Btu (th)/second

Converting Terawatt (TW) to Btu (th)/second (Btu (th)/s) is a core calculation in Power, which measures the rate of energy expenditure, conversion, or work transfer per unit of time. This calculation navigates the boundary between the International Metric System (SI) and British Imperial / US Customary engineering standards. In contemporary metrology, Imperial units are defined in terms of exact SI standards via international agreements—notably NIST SP 811 and the 1959 International Yard and Pound Agreement. Exactly 1 Terawatt equals 9.484514 × 10⁸ Btu (th)/second, while 1 Btu (th)/s equals 1.05435 × 10⁻⁹ TW.

Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (watt (W)) without arbitrary rounding:

V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)

Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)

1. Source SI Bridge (k_source):1 TW = 1 × 10¹² watt (W)

2. Target SI Bridge (k_target):1 Btu (th)/s = 1054.350264 watt (W)

Step-by-step substitution for Terawatt → Btu (th)/second:V(Btu (th)/s) = V(TW) × ( 1 × 10¹² / 1054.350264 ) = V(TW) × 9.484514 × 10⁸

Mathematical FormulaValue in Btu (th)/second = Value in Terawatt × 9.48451415 × 10⁸Direct computational formula applied for standard conversion.

Worked Example

For an engineering input of 15 TW, applying the conversion factor yields exactly 1.422677 × 10¹⁰ Btu (th)/s. At larger operational scale, 10000 Terawatt corresponds to 9.484514 × 10¹² Btu (th)/s.

Inverse check: 1 Btu (th)/s = 1.05435 × 10⁻⁹ TW.
