BMI = 23 kg/grand² ( Normal )

• Salubrious BMI range: 18.5 kg/one thousand² - 25 kg/g²
• Salubrious weight for the elevation: 128.ix lbs - 174.2 lbs
• Ponderal Index: 12.9 kg/1000³

The Body Mass Index (BMI) Calculator can be used to calculate BMI value and respective weight status while taking age into consideration. Use the "Metric Units" tab for the International System of Units or the "Other Units" tab to catechumen units into either Us or metric units. Annotation that the calculator also computes the Ponderal Index in addition to BMI, both of which are discussed below in particular.

BMI introduction

BMI is a measurement of a person's leanness or corpulence based on their height and weight, and is intended to quantify tissue mass. It is widely used as a general indicator of whether a person has a healthy body weight for their summit. Specifically, the value obtained from the calculation of BMI is used to categorize whether a person is underweight, normal weight, overweight, or obese depending on what range the value falls between. These ranges of BMI vary based on factors such equally region and age, and are sometimes farther divided into subcategories such as severely underweight or very severely obese. Being overweight or underweight can accept significant health effects, and so while BMI is an imperfect measure of healthy torso weight, it is a useful indicator of whether any additional testing or action is required. Refer to the table below to see the different categories based on BMI that are used by the estimator.

BMI table for adults

This is the World Health Organization'south (WHO) recommended torso weight based on BMI values for adults. It is used for both men and women, age xviii or older.

Category	BMI range - kg/mii
Astringent Thinness	< sixteen
Moderate Thinness	16 - 17
Balmy Thinness	17 - xviii.5
Normal	eighteen.5 - 25
Overweight	25 - thirty
Obese Class I	30 - 35
Obese Form II	35 - 40
Obese Class Iii	> 40

Risks associated with being overweight

Being overweight increases the risk of a number of serious diseases and health conditions. Below is a listing of said risks, according to the Centers for Disease Control and Prevention (CDC):

• High claret pressure
• Higher levels of LDL cholesterol, which is widely considered "bad cholesterol," lower levels of HDL cholesterol, considered to exist practiced cholesterol in moderation, and high levels of triglycerides
• Type 2 diabetes
• Coronary eye disease
• Stroke
• Gallbladder disease
• Osteoarthritis, a type of joint illness caused past breakdown of joint cartilage
• Slumber apnea and breathing problems
• Certain cancers (endometrial, breast, colon, kidney, gallbladder, liver)
• Low quality of life
• Mental illnesses such as clinical depression, anxiety, and others
• Trunk pains and difficulty with certain physical functions
• Generally, an increased run a risk of bloodshed compared to those with a healthy BMI

Every bit tin can be seen from the listing above, in that location are numerous negative, in some cases fatal, outcomes that may event from being overweight. More often than not, a person should try to maintain a BMI beneath 25 kg/chiliadⁱⁱ, but ideally should consult their doctor to determine whether or non they need to make any changes to their lifestyle in order to be healthier.

Risks associated with existence underweight

Being underweight has its own associated risks, listed below:

• Malnutrition, vitamin deficiencies, anemia (lowered ability to carry blood vessels)
• Osteoporosis, a affliction that causes bone weakness, increasing the risk of breaking a bone
• A decrease in allowed function
• Growth and development problems, particularly in children and teenagers
• Possible reproductive issues for women due to hormonal imbalances that can disrupt the menstrual cycle. Underweight women also have a higher chance of miscarriage in the first trimester
• Potential complications every bit a result of surgery
• By and large, an increased run a risk of mortality compared to those with a healthy BMI

In some cases, being underweight tin can be a sign of some underlying condition or disease such every bit anorexia nervosa, which has its own risks. Consult your doctor if you lot remember you or someone you know is underweight, particularly if the reason for being underweight does not seem obvious.

Limitations of BMI

Although BMI is a widely used and useful indicator of healthy body weight, it does have its limitations. BMI is just an estimate that cannot accept body composition into account. Due to a wide variety of body types every bit well as distribution of muscle, bone mass, and fat, BMI should be considered along with other measurements rather than beingness used every bit the sole method for determining a person's healthy body weight.

In adults:

BMI cannot exist fully accurate because information technology is a measure out of backlog body weight, rather than excess torso fatty. BMI is further influenced by factors such equally age, sex, ethnicity, muscle mass, and body fat, and activity level, amidst others. For example, an older person who is considered a salubrious weight, merely is completely inactive in their daily life may accept significant amounts of excess body fatty even though they are not heavy. This would exist considered unhealthy, while a younger person with higher musculus composition of the same BMI would be considered good for you. In athletes, particularly bodybuilders who would exist considered overweight due to muscle being heavier than fat, it is entirely possible that they are really at a healthy weight for their body composition. Generally, co-ordinate to the CDC:

• Older adults tend to take more than trunk fatty than younger adults with the same BMI.
• Women tend to have more body fatty than men for an equivalent BMI.
• Muscular individuals and highly trained athletes may have higher BMIs due to big muscle mass.

In children and adolescents:

The same factors that limit the efficacy of BMI for adults tin can too apply to children and adolescents. Additionally, elevation and level of sexual maturation can influence BMI and body fat among children. BMI is a better indicator of backlog body fat for obese children than information technology is for overweight children, whose BMI could be a result of increased levels of either fatty or fatty-free mass (all trunk components except for fatty, which includes water, organs, muscle, etc.). In thin children, the difference in BMI can likewise exist due to fatty-free mass.

That being said, BMI is fairly indicative of body fatty for 90-95% of the population, and tin effectively be used along with other measures to help determine an individual's healthy body weight.

BMI formula

Below are the equations used for calculating BMI in the International Organization of Units (SI) and the United states of america customary system (USC) using a 5'x", 160-pound individual as an example:

USC Units:

BMI = 703 ×

= 703 ×

= 22.96

SI, Metric Units:

Ponderal Alphabetize

The Ponderal Index (PI) is like to BMI in that it measures the leanness or corpulence of a person based on their top and weight. The main difference between the PI and BMI is the cubing rather than squaring of the height in the formula (provided below). While BMI can be a useful tool when considering large populations, it is not reliable for determining leanness or corpulence in individuals. Although the PI suffers from similar considerations, the PI is more reliable for employ with very alpine or curt individuals, while BMI tends to record uncharacteristically high or low trunk fat levels for those on the extreme ends of the meridian and weight spectrum. Below is the equation for computing the PI of an private using USC, again using a 5'ten", 160-pound individual every bit an example:
