Engineering conversions
Fast, professional unit conversions for checks, specs, and day-to-day site + design coordination.
Keep calculations consistent across drawings, specifications, supplier data sheets, and client reporting.
MPa/kPa ↔ PSI conversions for system pressures, material properties, and test results.
N/kN ↔ lbf for structural loads, mechanical calcs, and reference charts.
kg/m³ ↔ lb/ft³ for specifications and cross-standard documentation.
Calculators & advanced tools
More engineering calculators can be added here as the category expands.
Always confirm whether a spec expects force (lbf) vs mass (lbm), and use a consistent rounding policy for reporting. For pressure, keep an eye on gauge vs absolute values (units convert, reference states do not).
Primary converters
High-use engineering conversions, organized for quick access.
Common for mechanical/civil specs: convert MPa values (e.g., material strength, system pressure) into PSI for imperial documentation.
Convert PSI readings into MPa for calculations, reports, and standards that specify pressure in SI units.
Common in HVAC and industrial specs: convert bar into PSI for imperial documentation and equipment ratings.
Convert PSI into bar for SI/European specifications, datasheets, and calculations.
Quick SI pressure conversion: 1 bar = 100 kPa. Useful for system pressures and equipment specs.
Convert kPa into bar for compact SI reporting and European-style pressure specs.
Convert bar into MPa when pressure values are specified in megapascals (e.g., material or system ratings).
Convert MPa into bar for compact SI reporting (1 MPa = 10 bar).
Use for low/medium pressure systems (HVAC, pneumatics, fluid systems) when your data is in kPa but reporting needs PSI.
Convert PSI to kPa for SI-based engineering calculations and equipment specs.
Translate SI forces (N) into lbf for legacy charts, imperial calculations, and field documentation.
Convert lbf into newtons for SI-based engineering equations and analysis.
Useful in structural engineering: convert kN loads into lbf for imperial load tables and calculations.
Convert lbf loads into kN for SI-based structural calculations and reporting.
Convert material density from SI to imperial units for specs, datasheets, and cross-standard engineering documentation.
Convert density from lb/ft³ into kg/m³ for SI-based calculations and reports.
