BMI in SI units = Weight in kg / ( Height in meters )^{2}
BMI in US units= 703 X Weight in lbs / ( Height in inches )^{2}
BMI in UK units= 6.35 X Weight in kg / ( Height in meter )^{2}

**Consider your weight to be 80 kgs and height 152 cms. **

#### SI Units

Weight in kg / ( Height in meters )^{2}

= 80 / (1.52) ^{2}

Your body mass index in SI units is 34.63.

#### US Units

703 X Weight in lbs / ( Height in inches )^{2}

= 703 * 176 / (59.84) ^{2}

Your body mass index in US units is 35.21.

#### UK Units

6.35 X Weight in kg / ( Height in meter )^{2}

= 6.35 * 80 / (1.52) ^{2}

Your body mass index in UK units is 219.9.
