Calculator
Flow Converter
Convert flow between L/min, L/s, m3/h, mL/min, and US gpm.
Calculator Inputs
Legend
Flow conversion legend
Each flow value is converted through liters per minute as the base unit.
Input meaning
- Flow 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 volumetric flow does not correct for pressure, temperature, gas density, or standard conditions.
- Use calibrated flow analyzers for acceptance and PM.
Assumptions
- Gas flow conversions assume equivalent volumetric flow units.
- Clinical flow settings should be verified on calibrated devices.
Biomedical use
- Useful for oxygen planning, RO flow review, medical air/vacuum discussions, and service 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 |
|---|---|---|---|
| Flow value | Oxygen flowmeter set to 10 L/min. | Enter the source value exactly as shown before selecting the source and target units. | Enter the source value before converting units. |
| From | m3/h from compressor datasheet. | Select the unit printed on the source document or instrument. | Select the unit printed on the source document. |
| To | Convert m3/h to L/min for medical gas demand planning. | 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.
- Gas flow conversions assume equivalent volumetric flow units.
- Clinical flow settings should be verified on calibrated devices.
