Relationship between weight and mass

Directly proportional

Equation to calculate weight

W=m×gW = m \times g

Unit of measurement for weight (WW)

Newtons (N)

Unit of measurement for mass (mm)

Kilograms (kg)

Unit for gravitational field strength (gg)

Newtons per kilogram (N/kg)

Formula to calculate mass from weight

m=W÷gm = W \div g

Formula to calculate gg from weight and mass

g=W÷mg = W \div m
