If you are at 50^th percentile, you are close to the average weight.
At 90^th percentile, your weight is greater than 90% of others.
At 20^th percentile, then 80% of others weigh more than you.

Are you overweight? Maybe Body Mass Index says you are, but actually you are not. BMI can be wrong. Look at the weight percentiles, because they adjust for age.

The older you get, the higher your BMI is allowed to be. For example, in people over age 50, BMI of 25 to 30 is still normal and very healthy. I also believe the 45th percentile weight is a good estimate of your ideal weight.

Also, these height and weight charts and BMI charts show what the average population is like.

Why do I have two versions of a BMI calculator on halls.md? It's a leftover from year 2000, and I can't bring myself to delete old pages. So this page reminds me of the old-school html with tables, while the main BMI calculator is where new features will continue to appear. Some people like this one, with no graphics.

Way back in year 2000 when I created all this BMI stuff, calculators and analysis and custom formulas, the CDC was lagging. But to their credit, the science and their webpages and calculators have become quite good. You can unfortunately still find rigid categories on CDC pages like this but, they have more useful things like a BMI percentiles calculator for children, which, reminds me to mention because it's not obvious: my Weight Percentiles calculator is VERY equivalent to a BMI percentile.

Recently I've been looking at other BMI calculators, for instance at Mayo Clinic, which disappoint me, not only because of the ads for their branded diet, but they refer to a 2013 WHO report, where various academics still lump together overweight and obesity into 'combined', which of course is less healthy than normal weight. Whenever you read a study abstract where the word "combined" is used in confusing ways, that's deliberate tricky wordsmithing.

Is this usable for kids?

Yes. Male or Female gender, adult or child, girls or boys, teenagers, pediatric usage is fine.
For under 18 year old, this calculator does very well.
Soon I will implement better adjustments for men over 50 or women.

Is this applicable in different countries?

Yes, it's useful in the USA, u.s., Canada, India, Philippines, Queensland, NZ and UK.

Preferences for units?

It has metric kg and cm, with age adjustments, advanced and accurate and can show 2 decimal points, and is quick online.
Imperial in pounds and inches, lbs and feet units measurements. Doesn't have stone yet. Perhaps I should.

By the way, this used to be titled detailed and Advanced bmi calculator, but I'm trying out a new title, which I hope isn't too confusing. I think it compares favorably to offical range or other popular bmi calculators like

nih, nhs, navy, oxford, kidshealth, ymca, webmd, yahoo, etc.

Of course you know that...

without using waist size,
and not with muscle size,
not using body frame size, type or including bone structure
or other equation enhancements,

...BMI is too simple. You and I and everyone knows that BMI is too simple.

I wouldn't recommend using BMI in the normal way during pregnancy. Realistic weight gain is to be expected. Follow my links to a bmi chart, graph and you can find information about Females, body fat, weight loss and goals, and so on. I have references pertaining to young adults, Asian considerations, anorexia and eating disorders, health concerns of diabetes, and equation usage and work by dietitions. But I'm not showing results of obese class, reverse calculation, z-score, calories, visual gimicks, quiz or youtube cats here.
