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

Convert BTU to BTU 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) = BTU per second (BTU/s) × 0.000278

To convert BTU per hour (BTU/h) to BTU per second (BTU/s), multiply the value by 0.000278. 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 BTU/s.

Step 1: Write the formula: BTU/s = BTU/h × 0.000278
Step 2: Substitute: 1 × 0.000278
Step 3: Result: 0.000278 BTU/s

So, 1 BTU/h = 0.000278 BTU/s.
