Understanding Body Mass Index (BMI)
Body Mass Index is a widely used metric to assess whether a person has a healthy body weight for their height. The BMI is calculated using weight in kilograms and height in meters. Knowing your weight in kg simplifies this calculation:
BMI = weight (kg) / (height (m))2
For example, a person weighing 89.81 kg with a height of 1.75 meters would have a BMI of:
89.81 / (1.75)^2 ≈ 29.4
This BMI indicates an overweight classification, depending on age and other factors.
