The body mass index was developed by Adolphe Quetelet sometime around the mid 1800s. BMI is used to calculate or estimate what healthy weights of each individual should be so as to help people and doctors determine if a person’s weight is healthy or not. This concept tries to determine healthy weight in relation to a person’s height. For example, the BMI formula can be used to calculate a woman’s body mass index and the resulting index is then compared to the BMI chart to determine if it falls within the ideal BMI for women.

The BMI concept is very easy to calculate and is very useful for different applications. A person who is trying to lose weight can use their body mass index to keep track of their progress. It is very easy to calculate and there are several BMI calculators online that you can use. You just input the necessary weight and height information and the calculator does the rest. You can then use the index to compare on the BMI chart to see if you fall under the ideal bmi for women.

If you do not have access to a BMI calculator you can calculate your BMI manually. The formula is quite simple as explained below.

Multiply your weight (in pounds) by 703

Divide the answer by your height (in inches)

Divide the answer by your height (in inches) again

For example, we could calculate the BMI of a woman that weighs 280 pounds and is 72 inches tall using this simple formula.

280 (weight in pounds) multiply 703 = 196840

196840 divide 72 (height in inches) = 2733.9

2733.9 divide 72 = 38

Based on the calculation, her body mass index is 38 and we can use that index to check the BMI chart to discover that she is obese.

## What defines **the ideal bmi for women**?

The BMI concept doesn’t factor in the sex of the person and so the same formula and BMI chart used for both men and women is the same. What would be considered as the ideal body mass index for women is also the same for men. Generally, any BMI that is below 18.5 is considered to be underweight. BMI that falls within 18.5 and 24.9 is considered to be healthy and normal. Those with BMI between 25 and 29.9 are overweight and a BMI above 30 is considered to be obese. Any BMI over 40 is morbidly obese.

This means that the average male with average height of about 1.76m should weight between 130lbs and 165lbs to be considered normal. The average female with average height of about 1.62m should weight between 105lbs and 140lbs to be considered to have an the ideal body mass index for women.

### Everyone does agree that the body mass index is a very useful tool that experts and individuals can use to monitor their weight and health. Those who are trying to lose weight would find that BMI gives them a good way to monitor their progress and set goals for themselves. You can calculate your BMI right now to determine if you fall within **the ideal bmi for women** or if you need to take necessary steps to address your weight.

Health experts also use body mass index classifications to access patients to indentify those with conditions such as eating disorders. They can also use the BMI concept to educate people on how to keep check on their weight and improve their general health. Obesity and overweight people and health related problems are on the rise and a tool as the BMI is certainly a useful thing for people to learn how to put into use.
