Units & reference conditions
Change units on one basis, or explicitly convert a dry-air state.
New projects stay in memory until you choose Save or Export. Local saving is not a cloud account. Contacts are excluded from saved project files.
Calculations run on this device. A result is a preliminary estimate, not engineering approval. No documented model operating points have been imported yet.
Flow: m3/min, m3/h, L/s, cfm. Pressure: bar, kPa, Pa, psi. Temperature: C, F, K. Power: kW, W, hp-mechanical, hp-metric. Volume: m3, L, ft3. Gas state: Q₂=Q₁(P₁/P₂)(T₂/T₁)(Z₂/Z₁), absolute pressure and kelvin. No kW-to-flow conversion.
Required data & method sources
- Value, quantity and source/target units on the same flow basis
- Local absolute atmospheric pressure for gauge/absolute conversion
- For state conversion: both absolute pressures, temperatures and Z factors; confirmed unchanged dry air
Method references only; not manufacturer performance data or engineering approval.
- NIST SP 811 Appendix B.8 — Flow, pressure, power, volume and temperature entries
- Equation of State — Equation p V = n R T
