How can one determine body weight?

The calculation of body weight involves using the Body Mass Index (BMI). To calculate BMI, an individual's weight in kilograms (kg) is divided by their height in meters (m) squared. For example, if someone weighs 70 kg (equivalent to around 11 stone) and has a height of 1.73 m (approximately 5 feet 8 inches), their BMI can be calculated as follows: squaring their height by multiplying 1.73 by 1.73, which equals 2.99, and then dividing 70 by 2.99 to get a BMI of 23.41.

The formula for weight conversion is as follows: Pound (lbs) / 2.2046 = Result in Kilograms (kg). Additionally, Kilograms (kg) x 2.2046 = Result in Pound (lbs). For instance, 100 pounds (lbs) divided by 2.2046 equals 45.36 kilos (kg), while 100 kilos (kg) multiplied by 2.2046 equals 220.46 pounds (lbs).
