Height 64 Inches In Feet

Estimator Use

The BMI Figurer finds the body mass index given weight and height. Calculate your BMI and find the BMI weight category for your height. The calculator also finds the normal weight range given your summit.

Summate BMI with weight in pounds, stones or kilograms. Enter height in inches, feet and inches, meters or centimeters.

BMI Formulas

Divide weight by height squared to discover BMI. Note that you need to use kg and meters the standard units for the BMI formula are kg and meters. If you demand other units of measure the estimator will convert among units for you.

In metric units, using kg and meters:

\( \text{ BMI} = \dfrac{ \text{ weight in kg}}{ \text{ summit}^2 \text{ in 1000}} \)

BMI = weight ÷ height²

In metric units: BMI = weight (kg) ÷ summit² (meters)
In US units: BMI = weight (lb) ÷ heightⁱⁱ (inches) * 703

See additional BMI formulas below for accurate calculations in metric or purple units.

What is BMI?

The body mass index or BMI is a ratio of mass to height. Information technology is calculated as kg per square meter or pounds per square inch of height. Numeric BMI values stand for to weight categories including underweight, normal, overweight and obese.

BMI is used as an indicator of the relative healthiness of a person. The Centers for Disease Control (CDC) and the World Health Organization (WHO) recognize that people who are overweight or underweight are at higher run a risk for certain health conditions. BMI also enables health professionals to discuss bodyweight objectively with their patients.

Calculate Adult BMI

The CDC and WHO utilise the BMI range charts below to evaluate the weight of adults aged 20 and over given his or her peak. These ranges typically apply to Due north American and Eurpoean populations. Wikipedia lists alternative BMI ranges and categories for specific Asian populations. Cut-off points for specific international subpopulations may vary.

WHO Adult BMI Categories

< 16.0

Severely Underweight

xxx.0 - 34.nine

Moderately Obese

35.0 - 39.9

Severely Obese

It'south of import to keep in heed that the generic BMI chart above does not account for differences between men and women. It is also limited in evaluating bodyweight health in people of short stature, or those who accept very high musculus mass.

Calculate Child and Teen BMI

The CDC recommends using a BMI-for-historic period calculation in children and teens between two and 20 years of historic period. Children'due south body fat varies with age, and boys and girls abound at dissimilar rates. So while the BMI calculation is the aforementioned for boys and girls also as adults, there are separate BMI growth charts for boys and girls.

Child BMI Percentile Calibration

Underweight, below the 5th percentile

Salubrious weight, between the fifth and 85th percentiles

Overweight, between the 85th and 95th percentiles

Obese, equal to or greater than the 95th percentile

body mass index for boys 2 to 20 years old

CDC Female BMI Growth Chart

body mass index for girls 2 to 20 years old

How to Calculate BMI

Using metric units, where weight is in kilograms and peak is in meters, divide weight by meters squared.

In United states of america units, where weight is in pounds and summit is in inches, divide weight by inches squared. So multiply this effigy past 703.

Example 1: Calculate BMI in metric units

Matilda weighs 64 kg and is one.9 meters alpine. What is her BMI?

Divide 64 by 1.9²

BMI = due west ÷ h²
BMI = 64 ÷ 1.9²
BMI = 64 ÷ 3.61
BMI = 17.vii

Instance 2: Calculating BMI in The states units

Stanley weighs 184 lb and is 5 anxiety, x inches alpine. What is his BMI?

Find total inches by multiplying 5 * 12 and add x. Divide weight by total inches squared and multiply the consequence past 703.

v feet, 10 inches = 70 inches
BMI = (w ÷ h²) * 703
BMI = (184 ÷ 70²) * 703
BMI = (184 ÷ 4900) * 703
BMI = 0.3755 * 703
BMI = 26.four

Although BMI is calculated the same manner worldwide for all ages, the mode an individual's BMI is interpreted depends on location and the person's historic period.

In many Southeast Asian countries, the thresholds for the overweight and obese categories tend to exist lower. For example, in Singapore and Hong Kong a BMI of 23.0 is considered overweight, whereas in the United States a BMI of 25 is considered overweight.
Children and adolescents are not evaluated using these thresholds but are evaluated relative to others of the same age and gender. Run across the charts above.

Keep in mind that BMI is a ratio between pinnacle and total body weight - it does not differentiate between weight from muscle and weight from fat, nor does information technology consider an individual's body frame blazon. BMI is one of several tools used to assess a person's weight and overall health. If y'all are concerned well-nigh your weight, it is best to consult with your doctor or healthcare professional person.

Normal Weight Range

Normal weight BMI is xviii.5 to 24.9. To calculate your normal weight range use the following:

Metric units:
minimum weight (kg) = 18.five × summitⁱⁱ (m)
maximum weight (kg) = 24.nine × height² (m)
US units:
minimum weight (lb) = (xviii.5 ÷ 703) × heightⁱⁱ (in)
maximum weight (lb) = (24.9 ÷ 703) × acme² (in)
