How does the BMI calculator for men work?

You’ve been presented above with a weight calculation that is meant to provide you with a personalized BMI reading for your weight that will place your body mass in one of the functional ranges, as established by WHO. Data can be put in the form in the two main measurement systems used worldwide, metric and English or Imperial. Therefore you are asked for the weight in either kg or lbs and in height in meters or inches. The info you provide is then put in the BMI formula in order to give you the index. The height value is also used to determine which is the healthy weight range for that calculation. You can start the form for other data by pressing calculate again.

Body Mass Index

This is a weight indicator defined as the individual’s body mass in analysis with the body surface and is a way of determining how appropriate that weight is to the height given. BMI can be divided into several categories and generally the higher it is, the greater your risk of a large range of medical problems.

How to calculate BMI for males?

This is a calculation based on the body mass index formula, adapted for both metric and English measures. It isobtained through dividing the weight in kilograms by the square of the height in meters.

BMI= mass (kg)/height (m)^2

The conversions for the imperial measurement system are: 1 pound= 0.4535 kg, 1 inch= 0.0254 m or you can use the following BMI formula: mass(lb)/ height (in)^2 * 703

Example BMI calculation

For a male with a height of 6ft 1in and weighing 196 lbs, here is the BMI value:

BMI= 196/ 73^2 *703

BMI= 25.85 (rounded to 25.9)

This value is in the overweight range.

Interpreting the results

Repeating the same calculation in the BMI calculator for men will also provide the healthy weight range for the mentioned height. WHO generically classifies the BMI values as follows.

  • <18.5 Underweight
  • 18.5 - 25 Normal weight
  • 25 - 29 Overweight
  • >30 Obese
  • >40 Morbidly obese

This classification can provide useful information on the general weight state of an individual but also can portray sedentary levels within a population.

Why should men be interested in BMI?              

Because there have been numerous critics of the body mass index model and of its application that does not take age into account, people are inclined to consider it a soft measure of weight state and to leave it aside as a tool for women that are overly interested in measuring all kinds of bodily parameters.

Contrary to this belief, men should be equally interested in assessing their body mass condition, although this parameter doesn’t accurately discriminate between people with muscular builds and people with mainly adipose tissue.

This weight index is a great guideline to assess thinness or thickness of one’s body and changes that should or should not be made in lifestyle but also different health risks that come with different weights.

BMI implications for male population

Although it might not seem of a great importance when it is a low number, a body mass index of less than 18.5 can heighten the risk of developing nutritional deficiencies and osteoporosis. Also a great BMI can portray a series of risks that are higher and higher just as the number gets higher and assesses an obese body.

Measuring body fat has increasingly become a preoccupation in most Western societies as continuous research keeps showing that obesity is connected to a lot of health impairing conditions.

Individuals with a BMI value over 26 are at a higher risk of developing:

  • Cardiovascular diseases (stroke, high blood pressure, coronary disease)
  • Dyslipidemies (high LDL cholesterol, high triglycerides)
  • Respiratory problems (sleep apnea)
  • Cancer (i.e colon)
  • Type 2 Diabetes
  • Gallbladder disease
  • Metabolic diseases
