Convert Heat Transfer Coefficient Units Online with BTU per hour (BTU/h) to Calorie per second (cal/s) Conversion

Convert BTU to Calorie 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 hour (BTU/h) = Calorie per second (cal/s) × 0.070046

To convert BTU per hour (BTU/h) to Calorie per second (cal/s), multiply the value by 0.070046. 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/h to cal/s.

• Step 1: Write the formula: cal/s = BTU/h × 0.070046
• Step 2: Substitute: 1 × 0.070046
• Step 3: Result: 0.070046 cal/s

So, 1 BTU/h = 0.070046 cal/s.
