Enter the age, height, and weight into the calculator to determine the Schmitz value, which is an estimate of a person’s basal metabolic rate (BMR).

Schmitz Formula

The Schmitz formula is used to estimate the basal metabolic rate (BMR) of an individual based on their age, height, and weight. The formula is as follows:

BMR = 0.0047 * W + 0.0191 * H - 0.141 * A + 83.773

Variables:

  • BMR is the basal metabolic rate (Schmitz value)
  • W is the weight of the individual in kilograms (kg)
  • H is the height of the individual in centimeters (cm)
  • A is the age of the individual in years

To calculate the BMR using the Schmitz formula, multiply the weight by 0.0047, the height by 0.0191, subtract the product of the age and 0.141, and then add 83.773.

What is the Schmitz Formula?

The Schmitz formula is a method to estimate an individual’s basal metabolic rate, which is the amount of energy expended while at rest in a neutrally temperate environment. The BMR represents the minimum amount of energy needed to keep the body functioning, including breathing and keeping the heart beating. This formula takes into account the person’s age, height, and weight to provide an estimate of their BMR.

How to Calculate BMR using the Schmitz Formula?

The following steps outline how to calculate the BMR using the Schmitz Formula.


  1. First, determine the weight of the individual (W) in kilograms.
  2. Next, determine the height of the individual (H) in centimeters.
  3. Next, determine the age of the individual (A) in years.
  4. Next, gather the formula from above = BMR = 0.0047 * W + 0.0191 * H – 0.141 * A + 83.773.
  5. Finally, calculate the BMR (Schmitz value).
  6. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Weight (W) = 70 kg

Height (H) = 175 cm

Age (A) = 30 years
