How is BMI calculated and interpreted?
Calculation of BMI
The calculation is based on the following formulas:
Measurement units Formula/calculations
Kilograms and meters (or centimeters) Formula: weight (kg)
Since height is commonly measured in centimeters, hence divide height in centimeters by 100 to obtain height in meters.
Example: Height = 165 cm (1.65 m), Weight = 68 kg
Calculation: 68 ÷ (1.65)2 = 24.98
Pounds and inches Formula: weight (lb) / [height (in)]2 x 703
Calculate BMI by dividing weight in pounds (lbs) by height in inches (in) squared and multiplying by a conversion factor of 703.
Example: Weight = 150 lbs, Height = 5’5” (65″)
Calculation: [150 ÷ (65)2] x 703 = 24.96
Furthermore in conclusion, apart from body fat and other factors influence your health. These include diet, physical activity, smoking, blood pressure, cholesterol levels, and blood sugar levels. Most noteworthy to exercise, whatever your BMI, can help reduce your risk of cardiovascular disease and diabetes.
