Methodology
For factor-based categories, values pass through the configured base unit: base value = input value × source factor, then output value = base value ÷ target factor.

Quick Reference Table
| Unit | Converted to bar | bar converted to unit |
|---|---|---|
| psi | 1 psi = 0.068948 bar | 1 bar = 14.5038 psi |
| kPa | 1 kPa = 0.01 bar | 1 bar = 100 kPa |
| MPa | 1 MPa = 10 bar | 1 bar = 0.1 MPa |
| atm | 1 atm = 1.0132 bar | 1 bar = 0.986923 atm |
| mH₂O | 1 mH₂O = 0.098067 bar | 1 bar = 10.1972 mH₂O |
| kgf/cm² | 1 kgf/cm² = 0.980665 bar | 1 bar = 1.0197 kgf/cm² |
01
Engineering Basis
Assumptions
- Convert only between units in the same physical quantity family and with the same declared concentration or operating basis.
Scope / Limitations
- The converter normalizes units; it does not validate source data, infer a process basis, or replace the assumptions of a downstream model.
02
Engineering Path
Upstream Context
- Declared value and source unit Use the unit stated on the sample record, supplier sheet, or design note.
Current Tool Decision
- Pressure Unit Converter Convert within this quantity family while preserving the declared engineering basis.
Downstream Engineering Step
- Pipe Friction & Pressure Drop Calculator Use the normalized value in the relevant engineering calculation and verify its basis.
- Water Treatment Plant Hydraulic Profile Use the normalized value in the relevant engineering calculation and verify its basis.
- RO System Designer Use the normalized value in the relevant engineering calculation and verify its basis.
