BEHIND THE NUMBERS
Formula graph
Explore four connected physical relationships, their variables, compatible unit converters and twelve focused solve-for calculators.
Choose the unknown quantity to open a focused calculator, or use the general solver to switch between variables. Each relationship shares one calculation engine. All inputs use the SI units shown.
Distance, speed & time
distance = speed × time
Solve for
- Distance (m) — distance = speed × time
- Speed (m/s) — speed = distance ÷ time
- Time (s) — time = distance ÷ speed

Open the general solver →Density, mass & volume
density = mass ÷ volume
Solve for
- Density (kg/m³) — density = mass ÷ volume
- Mass (kg) — mass = density × volume
- Volume (m³) — volume = mass ÷ density
