How to Convert Btu (th)/second to Dekawatt

Converting Btu (th)/second (Btu (th)/s) to Dekawatt (daW) 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 Btu (th)/second equals 105.435026 Dekawatt, while 1 daW equals 0.00948451 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 Btu (th)/s = 1054.350264 watt (W)

2. Target SI Bridge (k_target):1 daW = 10 watt (W)

Step-by-step substitution for Btu (th)/second → Dekawatt:V(daW) = V(Btu (th)/s) × ( 1054.350264 / 10 ) = V(Btu (th)/s) × 105.435026

Mathematical FormulaValue in Dekawatt = Value in Btu (th)/second × 105.43502645Direct computational formula applied for standard conversion.

Worked Example

For an engineering input of 75 Btu (th)/s, applying the conversion factor yields exactly 7907.626984 daW. At larger operational scale, 2500 Btu (th)/second corresponds to 263587.566122 daW.

Inverse check: 1 daW = 0.00948451 Btu (th)/s.
