    The imperial formula is still wrong. I am 6\’0\” and I put in 6.0 and 151 lbs –> my bmi is 20.5 and it\’s telling me 17.4.

    How many people have been adversely affected by this??

    • Healthiack.com

      Thank you for notifying us. The bug has been fixed and the calculation now shows correct result.

    Thanks for this bmi calculator for men. I find it useful for my weight loss program.

  6. David

    The BMI calculator is little misleading if one didn’t read the details. Perhaps you should show the input as ” ft.ins ” instead of just inches alone. The first time I converted the total to inches and the value was erroneous.

  7. BW

    WEBSITE ERROR IN FORMULA
    Imperial data input screen currently (March 31, 2014) asks for

    Your height: in inches. Example 6.1.

    but calculates based on feet, giving inaccurate low result.

    Imperial users expect to enter [feet], [inches], as
    “I am [6] foot [1.5] inches tall.”
    which translates to “I am 73.5 inches tall.”

    • Healthiack

      We are sorry for any inconvenience. Please use only 2 digits when inputting height. For example if your height is 6 foot and 1.5 inches please input your height as 6 foot 2 inches. Calculation will still be 99% accurate.
