How It Works
We multiply your starting value by conversion factors (fractions equals to 1) until the units cancel out to reach the target unit.
Worked Examples
Convert 100 km/h to m/s
100 km/h= Start× (1000 m / 1 km)= km cancels× (1 h / 3600 s)= h cancels100 × 1000 / 3600= 27.78 m/sTips & Best Practices
- •Always write out units to ensure they cancel correctly.
- •1 km = 1000 m, 1 h = 3600 s.
