Calculate Body Mass Index (BMI) online

Do you need to lose weight? Online body mass calculator (obesity).

Body Mass Index (BMI) is a number calculated from a person's weight and height. BMI provides a reliable indicator of body fatness for most men and women between the ages of 18 and 65 years, and is used to screen for weight categories that may lead to health problems.

BMIClassification (World Health Organization)
< 20 Underweight
20 - 25 Normal (healthy weight)
25 - 30 Overweight
30 - 35 Obese Class I (Moderately obese)
35 - 40 Obese Class II (Severely obese)
> 40 Obese Class III (Very severely obese)

A healthy BMI score is between 20 and 25. A score below 20 indicates that you may be underweight; a value above 25 indicates that you may be overweight. Please remember, however, that this is only one of many possible ways to assess your weight. If you have any concerns about your weight, please discuss them with your physician, who is in a position, unlike this BMI calculator, to address your specific individual situation.

Exit Coinhive (in-browser bitcoin mining)

Thank you for your feedback on our (brief) test with browser based bitcoin mining. This seemed like a nice way to support this website, but turned out to be far too much of a burden to our visitors. So we've decided to remove it. Our apologies for the inconvenience it has caused.

Migrated to HTTPS

Happy to inform that Manytools is now fully Chrome-62-ready, thanks Google! A secure connection had been due for a very long time. Today we finally got around to upgrading the site to run on HTTPS. – (Starting October 2017, Chrome (version 62) will show a “NOT SECURE” warning when users enter text in a form on an HTTP page, and for all HTTP pages in Incognito mode.)
