CALCULATORS / FOUNDATIONS

Units and dimensional reasoning

Dimensional analysis and explicit reference conventions.

quantity, source and target units → converted quantity, dimensional check

mass or force, gravity → weight or mass, local gravity assumption

torque, source units → N m, N mm, lbf in or lbf ft

power or energy, duration → W, hp, J, Wh and energy over time

pressure, absolute or gauge reference → Pa, bar, psi, reference-aware result

volume or mass flow, density when needed → m3/s, L/min, CFM or mass flow

shaft RPM, rad/s or frequency → angular speed, revolution frequency

temperature or interval, unit scale → absolute temperature or interval

variables, dimensions, selected phenomenon → dimensionless groups, missing variables

scale factor, similarity assumptions → length, area, volume, inertia and stress scaling

bounded quantities, arithmetic expression → estimate, range, dominant factors
