P+P Engineering Converter

**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. --- **HIGHLIGHT-TO-CONVERT** Select any value on any webpage — a datasheet, a supplier spec, a test standard — right-click, and choose "Convert with P+P Converter." Results appear instantly in a floating panel without leaving the page. --- **ACCURACY** All conversions are based on internationally defined physical constants. No rounding during intermediate steps. Verified against NIST and ISO reference values. --- **AVAILABLE IN ENGLISH, GERMAN AND SPANISH** --- **ABOUT POPPE + POTTHOFF MASCHINENBAU** This tool is developed and maintained by Poppe + Potthoff Maschinenbau GmbH, a German manufacturer of customized high-pressure test benches and validation systems.
