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.
Published converter entries in this category.
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.
No. They are intended for education, estimation, and preliminary engineering checks. Critical work must be verified against applicable standards, validated software, and qualified professional judgment.
Routine calculators and converters run in the browser. File tools are designed for local browser-side processing unless a tool explicitly states otherwise.
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.
