Relationship between weight and mass

Directly proportional

Formula for weight

W=m×gW = m \times g

Unit for weight (WW)

Newtons (N)

Unit for mass (mm)

Kilograms (kg)

Unit for gravitational field strength (gg)

Rearranged formula to find mass

m=W÷gm = W \div g

Rearranged formula to find gg

g=W÷mg = W \div m
