What is a BTU per Second?

BTU per second (BTU/s) measures very high heat transfer rates. 1 BTU/s = 1,055 watts = 1.055 kW. Used for large power plants, industrial systems. Rare unit; MW or BTU/h × 1000 preferred.

History of the BTU per Second

Theoretical unit for very high-power applications. Rarely used in practice; megawatts (MW) or millions of BTU/h preferred for large systems. Engineering reference conversion.

Quick Answer

What is BTU/s? BTU per second (BTU/s) measures very high power. 1 BTU/s = 1,055 watts = 1.055 kW = 3,600 BTU/h. Used for large power plants, industrial processes. Rarely seen; MW more common. 1,000 BTU/s ≈ 1 MW. Use our power converter for conversions.

Definition

1 BTU/s = 1,055.06 W = 1.055 kW = 3,600 BTU/h = 1.41 hp = 0.001055 MW

Common Uses

Rare Unit: Almost never used in practice. Theoretical: Engineering textbooks, conversion tables. Alternatives Preferred: MW for large systems, BTU/h for HVAC. Historical: Old power plant references (now use MW).

Real-World Examples

Large Systems (if rated in BTU/s)

  • Large boiler (10 MW): ~9,478 BTU/s (34.1 million BTU/h)
  • Small power plant (100 MW): ~94,780 BTU/s (341 million BTU/h)
  • Industrial furnace (5 MW): ~4,739 BTU/s (17 million BTU/h)

Reality: These would actually be rated in MW or million BTU/h, not BTU/s.

Why BTU/s is Impractical

  • Large numbers: 10,000 BTU/s easier as 10.55 MW
  • Industry standards: Power plants always use MW
  • Confusion: Mixing BTU/s with BTU/h creates errors
