How to Convert Petawatt to Btu (th)/second

Converting Petawatt (PW) 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 Petawatt equals 9.484514 × 10¹¹ Btu (th)/second, while 1 Btu (th)/s equals 1.05435 × 10⁻¹² PW.

Direct Factor1 PW = 9.484514 × 10¹¹ Btu (th)/s

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 PW = 1 × 10¹⁵ watt (W)

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

Step-by-step substitution for Petawatt → Btu (th)/second:V(Btu (th)/s) = V(PW) × ( 1 × 10¹⁵ / 1054.350264 ) = V(PW) × 9.484514 × 10¹¹

Mathematical FormulaValue in Btu (th)/second = Value in Petawatt × 9.48451415 × 10¹¹Direct computational formula applied for standard conversion.

Worked Example

Converting 15 PW yields an exact output of 1.422677 × 10¹³ Btu (th)/s in Btu (th)/second. Under higher industrial throughput, 480 PW translates to 4.552567 × 10¹⁴ Btu (th)/s.

Inverse check: 1 Btu (th)/s = 1.05435 × 10⁻¹² PW.
