Calculator

Electrical Unit Converter

Convert common electrical power units used in biomedical and facilities planning, including W, kW, VA, kVA, hp, and BTU/hr.

Electrical Unit Converter guidance

Values are converted through watts as the base unit. VA and kVA are treated as apparent-power units without power-factor correction.

Input meaning

  • Electrical value: enter the measured, quoted, or hospital-approved value.
  • From: select the option that matches the source document, device label, certificate, or installed system.
  • To: select the option that matches the source document, device label, certificate, or installed system.

Result interpretation

  • Use the result as a planning estimate, not as a final approval by itself.
  • Record the assumptions used so Procurement, Biomedical, Facilities, Finance, and vendors can review the same basis.

Assumptions

  • Use power factor when converting between real power and apparent power for final electrical design.
  • Do not use simple unit conversion for code-compliant electrical sizing.

Biomedical use

  • Use this calculator during RFQ preparation, technical evaluation, acceptance planning, service review, or biomedical workload planning.

How to identify the required values

Use these examples and common working ranges to choose values from gauges, labels, manuals, datasheets, RFQs, service reports, CMMS records, or hospital planning assumptions.

FieldExample valueCommon rangeTip
Electrical valueExample: 1.Enter the source value exactly as shown before selecting the source and target units.Enter the source value before converting units.
FromExample: W.Select the unit printed on the source document or instrument.Select the unit printed on the source document.
ToExample: W.Select the unit required in the RFQ, service report, or engineering calculation.Select the unit required in the output.

Common ranges are starting points for hospital planning. For final procurement, acceptance testing, electrical design, medical gas design, radiation shielding, dialysis water systems, or clinical use, replace the example values with site-specific data and vendor-confirmed figures.

Input Checklist

Confirm these values before relying on the output for procurement, PM, or service planning.

Safety And Engineering Notes

Use calculator outputs as planning estimates and verify critical systems with calibrated measurement or qualified engineering review.

  • Use power factor when converting between real power and apparent power for final electrical design.
  • Do not use simple unit conversion for code-compliant electrical sizing.
