Power is energy per time; watts relate to horsepower and BTU/h with standard factors. Use it for appliances, motors, and HVAC capacity.

How to use this calculator

  • Set inputs: Read the rating in the unit printed.
  • Pick units: Convert to compare across catalogs.
  • Verify: Check whether the rating is electrical input or mechanical output.

Real-world examples

  • Example: 1500 W ≈ 2.01 hp (mechanical, using 745.7 W/hp).
  • Round-trip check: Convert the result back to the starting unit—if you do not land near your original value within rounding, confirm you picked the right direction (e.g., A→B vs B→A).

Short explanation

Nameplate max vs average load differ—conversion does not change duty cycle.

FAQ

Are power unit converter results exact?

Fixed definitions (e.g., inches to cm) are exact. Values that depend on standards or rounding may differ slightly by display precision.

Why pick this hub instead of a single pair page?

Pair pages target one direction and one jump; this power unit converter hub matches the multi-unit converter card where you can switch units freely.

How accurate is this conversion?

It uses the standard fixed conversion factor for these units. Results are exact to the precision shown, aside from normal floating-point rounding.
