Editor's review of What Health BMI Calc

4 Star Rating

"Though it doesn't sport the most exciting design, this program quickly calculates your body mass index. You don't even have to install What Health BMI Calc--just unzip and run it. Its no-frills, compact interface has fields to enter height and weight. Both English and metric measurements are supported, so you don't have to do any conversions. Hit Calculate and your BMI and weight status are displayed. You won't find a Help file, but one isn't justified for a program as simple as What Health BMI Calc. If you want your own BMI calculator, this is an easy-to-use, if utilitarian, option that is offered free of charge."
