Convert Heat Transfer Coefficient Units Online with BTU per second (BTU/s) to Joule per second (J/s) Conversion

Convert BTU to Joule using the exact conversion factor. This page provides the formula, reference values, and practical context for engineering, technical calculations, and professional measurement use.

Conversion Formula

BTU per second (BTU/s) = Joule per second (J/s) × 1055.06

To convert BTU per second (BTU/s) to Joule per second (J/s), multiply the value by 1055.06. The conversion factor is based on standardized unit definitions and is suitable for engineering analysis, system design, and professional measurement workflows.

Example

Convert 1 BTU/s to J/s.

• Step 1: Write the formula: J/s = BTU/s × 1055.06
• Step 2: Substitute: 1 × 1055.06
• Step 3: Result: 1055.06 J/s

So, 1 BTU/s = 1055.06 J/s.
