What is a BTU per Minute and a Electric Horsepower?

1 BTU/min = 17.58 W = 0.01758 kW = 60 BTU/h = 0.0236 hp = 1.055 kJ/min

1 hp(E) = 746 W = 0.746 kW = 1.0004 hp (mechanical) = 2,545 BTU/h

Difference from mechanical hp: 746 W vs 745.7 W (0.04% higher)

Note: The BTU per Minute is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Electric Horsepower belongs to the imperial/US customary system.

Common Uses and Applications: BTU/min vs hp(E)

Explore the typical applications for both BTU per Minute (imperial/US) and Electric Horsepower (imperial/US) to understand their common contexts.

Common Uses for BTU/min

Industrial Burners: Gas burners, process heaters (sometimes rated in BTU/min). Engineering: Conversion reference between BTU/h and BTU/s. Boilers: Small commercial boilers (though BTU/h more common). Rarely Used: Most applications use BTU/h or kW instead.

When to Use hp(E)

Electric Motors: Industrial motors, pumps, compressors (ratings in hp(E)). HVAC: Fan motors, blower motors (fractional to 10 hp). Manufacturing: Conveyor motors, machine tools (1-100 hp). Residential: Garage door openers, pool pumps (0.5-3 hp).

Additional Unit Information

About Electric Horsepower (hp(E))

How do I convert electric horsepower to watts?

Formula: W = hp(E) × 746

Examples:

  • 1 hp(E) = 746 W
  • 5 hp(E) = 3,730 W = 3.73 kW
  • 10 hp(E) = 7,460 W = 7.46 kW
  • 0.5 hp(E) = 373 W

What is the difference between electric and mechanical horsepower?

Electric HP (hp(E)): 746 W exactly (US electric motors) Mechanical HP (hp): 745.7 W (550 ft⋅lb/s, automotive standard)

Difference: 0.04% (practically identical)

Usage:

  • Electric motors → hp(E)
  • Engines (gas, diesel) → mechanical hp
  • International → kW preferred

Conversion: 1 hp(E) = 1.0004 hp (mechanical)

How much power does a 1 hp electric motor use?

Full load: 746 W input (if 100% efficient)

Realistic power draw (accounting for efficiency):

  • 50% efficiency: 1,492 W (1.5 kW)
  • 70% efficiency: 1,066 W (1.07 kW)
  • 85% efficiency: 878 W (0.88 kW)
  • 90% efficiency: 829 W (0.83 kW)

Example: 1 hp motor at 85% efficiency draws 878W. Running 8 hours = 7 kWh energy consumed.

Modern motors: 85-95% efficient. Older motors: 70-85%.

Why use hp(E) instead of kW?

US tradition: Motor industry established before SI metric adoption

Current practice:

  • US: Both hp(E) and kW used (hp(E) more common for small motors)
  • Europe/Asia: Primarily kW
  • International standards: Moving toward kW only

Nameplate labeling: Many US motors show both (e.g., "1 hp / 0.75 kW")

Conversion: Divide hp(E) by 1.341 to get kW

How do I size a motor for my application?

Basic formula: Required hp = (Torque × RPM) ÷ 5,252

Practical approach:

  1. Determine load requirements (torque, speed, duty cycle)
  2. Add safety factor: Multiply by 1.15-1.25 (15-25% margin)
  3. Select next standard size: 1/4, 1/3, 1/2, 3/4, 1, 1.5, 2, 3, 5, 7.5, 10 hp

Example: Application needs 0.8 hp → Add 25% = 1 hp → Select 1 hp motor

Avoid oversizing: Wastes energy, motors run inefficiently at low load.
