BMI Calculator (Body Mass Index)

Calculator Use

This calculator will determine Body Mass Index or BMI, given an individual ‘s weight and acme. Weight can be entered pounds, stones and pounds, or kilograms. Height can be entered in inches, feet and inches, meters, or centimeters .
This calculator will besides calculate and display the normal weight range for the stature entered .

Calculating BMI

BMI is a way of measuring a person ‘s burden relative to his or her altitude. BMI expresses how compact or thin a person is in elementary numeral terms, and allows doctors and other health professionals to discuss weight objectively on a standardized scale.

BMI Formulas

This BMI calculator converts units to satisfy the follow BMI formula calculations .

• Metric units:
  BMI = weight (kg) ÷ height2 (m)
• US units:
  BMI = (weight (lb) ÷ height2 (in)) * 703

Normal Weight Range

normal weight BMI is 18.5 to 24.9. To calculate your normal weight range use the be :

• Metric units:
  
  minimum weight (kg) = 18.5 × height2 (m)
  
  maximum weight (kg) = 24.9 × height2 (m)
• US units:
  
  minimum weight (lb) = (18.5 ÷ 703) × height2 (in)
  
  maximum weight (lb) = (24.9 ÷ 703) × height2 (in)

Example 1 (Calculating BMI in metric units)

Matilda weighs 64 kilogram and is 1.9 meters improbable. What is her BMI ?

• BMI = w ÷ h2
• BMI = 64 ÷ 1.92
• BMI = 64 ÷ 3.61
• BMI = 17.7

Example 2 (Calculating BMI in US units)

Stanley weighs 184 pound and is 5 feet, 10 inches tall. What is his BMI ?

• 5 feet, 10 inches = 70 inches
• BMI = (w ÷ h2) * 703
• BMI = (184 ÷ 702) * 703
• BMI = (184 ÷ 4900) * 703
• BMI = 0.3755 * 703
• BMI = 26.4

Below is a table of normally used BMI ranges in North America and Europe for persons aged 21 and older. Wikipedia lists more detail BMI categories .

Although BMI is calculated the same direction worldwide for all ages, the direction an individual’s BMI is interpreted depending on location and the person ‘s age :

• In many Southeast Asian countries, the thresholds for the overweight and obese categories tend to be 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 at all, but are evaluated relative to others of the same age and gender:

Keep in mind that BMI is a proportion between stature and sum body weight – it does not differentiate between weight from brawn and weight unit from fat, nor does it consider an individual ‘s body frame type. BMI is one of respective tools used to assess a person ‘s system of weights and overall health. If you are concerned about your weight, it is best to consult with your doctor or healthcare professional .
