How To Find The Bmi Value

BMI Calculator

Age	ages: 2 - 120
Gender	Male Female

Result

BMI = 23 kg/m^two ( Normal )

• Healthy BMI range: eighteen.v kg/m² - 25 kg/m²
• Healthy weight for the height: 128.9 lbs - 174.two lbs
• Ponderal Index: 12.9 kg/m³

The Body Mass Index (BMI) Reckoner can be used to calculate BMI value and corresponding weight condition while taking age into consideration. Use the "Metric Units" tab for the International Arrangement of Units or the "Other Units" tab to convert units into either US or metric units. Note that the reckoner also computes the Ponderal Index in addition to BMI, both of which are discussed below in detail.

BMI introduction

BMI is a measurement of a person's leanness or corpulence based on their tiptop and weight, and is intended to quantify tissue mass. It is widely used equally a general indicator of whether a person has a salubrious body weight for their height. Specifically, the value obtained from the adding 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 as region and age, and are sometimes further divided into subcategories such as severely underweight or very severely obese. Existence overweight or underweight tin have significant health effects, so while BMI is an imperfect mensurate of healthy body weight, information technology 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 calculator.

BMI table for adults

This is the Earth Health System's (WHO) recommended body weight based on BMI values for adults. It is used for both men and women, age 18 or older.

Category	BMI range - kg/mtwo
Severe Thinness	< 16
Moderate Thinness	16 - 17
Mild Thinness	17 - 18.5
Normal	18.v - 25
Overweight	25 - 30
Obese Class I	30 - 35
Obese Grade II	35 - 40
Obese Course III	> 40

The Centers for Disease Control and Prevention (CDC) recommends BMI categorization for children and teens between age two and 20.

Category	Percentile Range
Underweight	<five%
Healthy weight	5% - 85%
At risk of overweight	85% - 95%
Overweight	>95%

Risks associated with existence overweight

Existence overweight increases the risk of a number of serious diseases and wellness atmospheric condition. Below is a list of said risks, according to the Centers for Disease Control and Prevention (CDC):

• High blood pressure
• Higher levels of LDL cholesterol, which is widely considered "bad cholesterol," lower levels of HDL cholesterol, considered to be good cholesterol in moderation, and high levels of triglycerides
• Type Ii diabetes
• Coronary eye illness
• Stroke
• Gallbladder disease
• Osteoarthritis, a type of articulation illness caused by breakdown of joint cartilage
• Sleep 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
• Body pains and difficulty with certain physical functions
• Generally, an increased risk of mortality compared to those with a healthy BMI

Equally can be seen from the list in a higher place, there are numerous negative, in some cases fatal, outcomes that may result from being overweight. More often than not, a person should try to maintain a BMI below 25 kg/m^two, but ideally should consult their dr. to determine whether or non they need to make whatever changes to their lifestyle in order to exist healthier.

Risks associated with being underweight

Being underweight has its own associated risks, listed below:

• Malnutrition, vitamin deficiencies, anemia (lowered ability to behave blood vessels)
• Osteoporosis, a disease that causes bone weakness, increasing the adventure of breaking a bone
• A subtract in immune function
• Growth and development bug, specially in children and teenagers
• Possible reproductive issues for women due to hormonal imbalances that can disrupt the menstrual wheel. Underweight women too have a higher chance of miscarriage in the first trimester
• Potential complications equally a event of surgery
• Generally, an increased adventure of mortality compared to those with a healthy BMI

In some cases, being underweight tin can exist a sign of some underlying condition or illness such as anorexia nervosa, which has its own risks. Consult your doctor if yous think yous or someone you lot know is underweight, specially if the reason for beingness underweight does non 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 merely an estimate that cannot take body composition into account. Due to a broad diverseness of trunk types also as distribution of muscle, bone mass, and fatty, BMI should be considered along with other measurements rather than being used as the sole method for determining a person's healthy body weight.

In adults:

BMI cannot be fully accurate because it is a mensurate of backlog body weight, rather than excess body fat. BMI is further influenced by factors such equally age, sexual activity, ethnicity, muscle mass, and body fat, and activity level, among others. For example, an older person who is considered a healthy weight, just is completely inactive in their daily life may take significant amounts of excess body fatty even though they are not heavy. This would be considered unhealthy, while a younger person with higher muscle composition of the same BMI would be considered healthy. In athletes, particularly bodybuilders who would be considered overweight due to muscle being heavier than fatty, it is entirely possible that they are actually at a healthy weight for their trunk composition. Generally, according to the CDC:

• Older adults tend to take more body fat than younger adults with the aforementioned BMI.
• Women tend to have more body fat than men for an equivalent BMI.
• Muscular individuals and highly trained athletes may accept higher BMIs due to large musculus mass.

In children and adolescents:

The same factors that limit the efficacy of BMI for adults can as well apply to children and adolescents. Additionally, top and level of sexual maturation can influence BMI and trunk fat amidst children. BMI is a amend indicator of excess torso fatty for obese children than it is for overweight children, whose BMI could be a result of increased levels of either fatty or fat-free mass (all body components except for fat, which includes water, organs, muscle, etc.). In thin children, the difference in BMI can also exist due to fat-free mass.

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

BMI formula

Below are the equations used for calculating BMI in the International Arrangement of Units (SI) and the U.s.a. customary system (USC) using a 5'x", 160-pound individual as an case:

USC Units:

BMI = 703 ×

= 703 ×

= 22.96

SI, Metric Units:

Ponderal Index

The Ponderal Alphabetize (PI) is similar to BMI in that information technology measures the leanness or corpulence of a person based on their meridian and weight. The main difference between the PI and BMI is the cubing rather than squaring of the peak in the formula (provided below). While BMI can be a useful tool when because big 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 use with very alpine or brusque 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 calculating the PI of an individual using USC, again using a 5'10", 160-pound individual as an example:
