This bmi calculator calculates body mass index from your Weight and Height and also shows how your weight compares to others of the same height and age.
Maintaining a healthy body weight is very important to all aspects of well being. It can help you avoid serious health problems such as heart disease and type 2 diabetes.
One way of checking if you are at a healthy weight is to know your Body Mass Index (BMI). Your body mass index bmi is calculated by dividing your weight in kilograms by your height squared in metres. But no need to worry about that, you can calculate your body bmi with the Halls BMI calculator above.
Simply enter your height, weight, gender and age. The BMI calculator will tell you if you have a high bmi, a low bmi or if you are within the healthy weight range. It also shows you how your weight compares to others of the same height and age.
Are you overweight? Maybe, if you get a bmi calculation that indicates you are, this may not always be accurate. Body Mass Index (BMI) can be misleading. This is because the BMI does not take into account your body composition. For example, your body fat percentage in comparison to your percentage of muscle mass is an important factor. Check out the mathematical formula to check your body fat percentage.
An important area to look at is the weight percentiles, because they adjust for age and gender.
The older you get, the higher your BMI is allowed to be. For example, in people over age 50, a BMI score of 25 to 30 is still normal and indicates a healthy weight. I also believe the 45th percentile weight is a good estimate of your ideal weight.
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 my body mass index calculator with 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. This 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'. This 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?
Is this applicable in different countries?
Preferences for units?
By the way, this used to be titled detailed and Advanced bmi calculator, but I'm trying out a new title. I hope it isn't too confusing. I think it compares favorably to offical range or other popular bmi calculators like
Here are things you already know.
BMI is too simple. You and I and everyone knows the BMI formula is too simple, although its a useful screening tool.
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. Links to 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.
Some other websites offer a bmr calculator, which is basal metabolic rate, and kudos to them for doing so. Some have ways of considering waist size, that is, waist circumference.
A DEXA scan can provide total body fat and lean muscle mass results, but that's a medical test that's hard to arrange.
BMI is a form of weight-to-height ratio, and is poor estimate of body fatness. Yes, it tells you something about health risk, and has mild predictive ability regarding chronic disease. But between overweight or obese, it's the higher levels of obesity that make a difference.
Have you heard of metabolic syndrome? It's increased blood pressure, high blood sugar, excess body fat around the waist. It also has abnormal cholesterol or trigliceride levels, which have somewhat increased risk of having heart disease, type diabetes and stroke.
One thing I dislike about health information on the internet, is the glib assertion that people should just do aggressive lifestyle changes. In order to lose weight and prevent serious health problems, supposedly. The reality of our lives is that long term weight loss is very difficult to maintain.
Which brings up the topic of the Talking Moose software. It's designed for long-term daily reinforcement of motivation for achieving and maintaining weight loss.
Body Mass Index scores are a good indicator of whether you are at a healthy weight and how much body fat you have. Having a high bmi can increase your risk factors for certain diseases such as cardiovascular disease (or heart disease), high blood pressure and diabetes type 2.
The National Institute of Health (nih gov) use BMI scores to determine if you qualify for weight loss surgery. For those with a BMI of over 40 qualify for weight loss surgery. Or, those with a bmi range of over 35 with related health conditions (heart disease, diabetes type 2, sleep apnea and high blood pressure). This link has a research based look at the pros and cons of weight loss surgery.
