Formula Triangles

To get any of the three quantities as the subject of the formula, cover it up in the formula triangle and put whatever remains on the other side of the triangle.

Speed

Speed

  • Speed is the distance travelled per unit of time.
  • Common units for speed are kilometres per hour (km/h), miles per hour (miles/h or mph) and metres per second (m/s).
Density

Density

  • Density is the mass per unit of volume.
  • Common units for density are kg/m3 and g/cm3.
Pressure

Pressure

  • Pressure is force acting per unit of area.
  • Common units for pressure are N/m2 or pascals (Pa).
