BMI Calculator

Body Mass Index

Body weight is a major influence on health throughout life. Obese people are generally less healthy and are more prone to illnesses such as diabetes, hypertension, heart diseases, gall bladder diseases and arthritis. Weigh yourself regularly and know your desirable body weight. Weigh yourself at least twice a month at the same time of the day wearing light clothing. Calculate your BMI by using the following formula:

BMI = Weight (kg) / [Height (m) x Height (m)]

You can check your weight status by using the BMI Calculator link below. The desirable BMI range for adult (aged 18 and above) is between 18.5 and 25.

BMR Calculator

Basal Metabolic Rate

You use energy no matter what you're doing, even when sleeping. The BMR Calculator will calculate your Basal Metabolic Rate (BMR); the number of calories you'd burn if you stayed in bed all day.

You can check your BMR by using the BMR Calculator link below.
