Engineering unit converters and calculation helpers with formulas, assumptions, and interpretation.
Use ScholarTool engineering utilities for pressure, force, stress, density, thermal, flow, and general engineering conversion workflows. Published tools normalize values to SI base units and explain the assumptions behind each result.
Convert Pa, hPa, kPa, MPa, GPa, bar, mbar, atm, Torr, mmHg, cmHg, inHg, psi, ksi, psf, N/mm^2, kgf/cm^2, kgf/m^2, and conventional water-column units with formulas and steps.
Convert Celsius, Kelvin, Fahrenheit, and Rankine values in separate absolute-temperature and temperature-difference modes.
Convert N, mN, kN, MN, dyn, gf, kgf, lbf, kip, and ozf with signed-force support.
Convert N·m, N·mm, kN·m, MN·m, kgf·m, kgf·cm, lbf·ft, lbf·in, and ozf·in.
Convert density units for CFD, FEA, materials, civil, and laboratory workflows.
Convert stress units such as MPa, N/mm^2, psi, ksi, kgf/cm^2, and kgf/mm^2 with compression/tension sign support.
Convert Pa·s, mPa·s, µPa·s, P, cP, kg/(m·s), g/(cm·s), lbm/(ft·s), lbm/(ft·h), and lbf·s/ft^2.
Convert m^2/s, mm^2/s, cm^2/s, St, cSt, ft^2/s, and in^2/s.
Convert volumetric flow rate units and clearly distinguish US GPM from Imperial GPM.
Convert thermal conductivity units while treating kelvin and Celsius intervals consistently.
Convert heat-transfer coefficient units for convection and U-value workflows.
ScholarTool category pages prioritize calculation context, unit discipline, assumptions, and interpretation so users can understand when a result is appropriate and when validated software or standards are required.
