Body Mass Index (BMI) Calculator

Check your BMI here.
Anyway, I'm using the standard formulation as widely used nowadays.

They are :
BMI (IM) =
( weight in lbs)

( height in inches )²
* ( 703 )
BMI (SI) =
( weight in kg )

( height in m )²
Both will give approximately-almost-the-same BMI score (if you convert the Imperial to SI or vice versa).
Actually, the constant multiplier number (for Imperial) is 703.06957964et cetera.
  • For Imperial unit, you can put your height number (ft and in) on those boxes - you don't have to type apostrophe or quote sign.
  • For the SI calculation, it's using centimeter (in the formulation) so you can easily put your height (in cm) without typing dot (.).
  • Double click text input to reset.
  • In Physics, weight and mass are different.

    Mass is a base quantity and weight is the derived quantity (the multiplication of mass and the gravitational acceleration).

    But, you know, to "simplify" everything, this tool is using weight quantity keyword, even though weight is actually using newton (N) unit.

    Hmm... I'll run away now

BMI Score

For example, your BMI score is 22. It means that you have a NORMAL (healthy weight) body category.
This table (and the "meaning" above) isn't necessarily 100% accurate. If you're a bodybuilder or a catwalk model or competitive eater or Sumo thingy or any extreme thingies (usually for TV or sumthin) out there, you guys will have different stories.
