P+P Engineering Converter

About

**11 ENGINEERING UNIT CATEGORIES TO CONVERT**

**Pressure**
bar, mbar, MPa, kPa, Pa, PSI, atm, N/mm², kgf/cm², Torr/mmHg
Essential for burst test targets, operating pressure specs, and OEM datasheets that mix bar and PSI without warning.

**Temperature**
°C, °F, K
For climate chamber settings, test fluid temperature specs, and material property lookups.

**Flow Rate**
L/s, L/min, L/h, mL/min, m³/s, m³/h, US gal/min, US gal/h, ft³/min
Covers pump sizing, cooling circuit design, and hydraulic system validation across metric and imperial specs.

**Force**
N, kN, MN, daN, lbf, kgf, tonne-force
For actuator sizing, clamping force calculations, and structural load specifications.

**Length**
µm, mm, cm, dm, m, km, inch, ft, yard, mile
From seal tolerances to test rig dimensions.

**Volume**
mL, cL, dL, L, cm³, mm³, m³, in³, ft³, fl oz, cup, US gallon, Imperial gallon
For fluid reservoir sizing and test fluid volumes.

**Frequency**
Hz, kHz, MHz, GHz, RPM, cycles/min, cycles/sec, rad/s
Direct relevance for pressure cycle testing — convert test frequency specs between Hz and cycles/minute instantly.

**Mass**
µg, mg, g, kg, metric tonne, oz, lb, stone, US short ton, UK long ton

**Power**
W, kW, MW, mW, hp (mechanical), PS (metric), BTU/h, BTU/s, kcal/h, kJ/h
For pump and drive unit sizing across US and European specs.

**Density**
kg/m³, g/cm³, g/mL, kg/L, t/m³, lb/ft³, lb/in³, lb/gal
For hydraulic fluid selection and test media characterisation.

**Viscosity**
mPa·s, Pa·s, cP, Poise, cSt, Stokes, mm²/s, m²/s, lbf·s/ft²
The category most unit converters skip. Critical for hydraulic fluid compatibility in high-pressure test systems.
