Calculator
Pressure Converter
Convert pressure between Pa, kPa, bar, psi, mmHg, and cmH2O.
Calculator Inputs
Legend
Pressure conversion legend
Each pressure value is converted to pascal as a base unit, then converted to the selected output unit.
Input meaning
- Pressure 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
- Converted values should be rounded according to instrument accuracy.
- Unit conversion does not confirm that a regulator, gauge, or transducer is calibrated.
Assumptions
- Round results appropriately for the instrument accuracy and application.
- Do not substitute unit conversion for calibrated testing.
Biomedical use
- Useful for medical gas, suction, ventilator, anesthesia, calibration, and utility documentation.
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.
| Field | Example value | Common range | Tip |
|---|---|---|---|
| Pressure value | Medical oxygen pipeline: 4 bar or about 400 kPa. | Enter the source value exactly as shown before selecting the source and target units. | Enter the source value before converting units. |
| From | psi from a cylinder gauge. | Select the unit printed on the source document or instrument. | Select the unit printed on the source document. |
| To | Convert psi to bar for a site utility schedule. | 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.
- Value
- From unit
- To unit
Safety And Engineering Notes
Use calculator outputs as planning estimates and verify critical systems with calibrated measurement or qualified engineering review.
- Round results appropriately for the instrument accuracy and application.
- Do not substitute unit conversion for calibrated testing.
