Inputs and labels to check before calculating

For BMR Calculator – Age 30, in this calculator configuration, this calculator uses the Mifflin-St Jeor identity Mifflin-St Jeor: 10W + 6.25H − 5A + s (s = +5 male / −161 female). The source configuration demonstrates male sex, age 30 years, height 170 cm, and weight 70 kg. Those values are useful for auditing the default output, but they should be replaced with the values relevant to the calculation you are performing.

Sex

For BMR Calculator – Age 30, in this calculator configuration, the selected sex determines the constant used by the supplied Mifflin-St Jeor expression. Treat this as a calculator input, not as a broader statement about identity. The safest workflow is to read the field label first, then enter the number exactly once.

Age

For BMR Calculator – Age 30, in this calculator configuration, age is a direct term in the equation. This page is configured around 30 years, so changing age while leaving the other sample inputs fixed changes the arithmetic. The safest workflow is to read the field label first, then enter the number exactly once.

Height

For BMR Calculator – Age 30, in this calculator configuration, height is supplied as 170 cm in the shipped example. Keep the unit consistent with the form; do not convert a value twice. The safest workflow is to read the field label first, then enter the number exactly once.

Weight

For BMR Calculator – Age 30, in this calculator configuration, weight is supplied as 70 kg in the example. Use the measurement requested by the calculator rather than substituting a target or desired weight. The safest workflow is to read the field label first, then enter the number exactly once.

Formula and calculation method

For BMR Calculator – Age 30, in this calculator configuration, the calculator identity is Mifflin-St Jeor: 10W + 6.25H − 5A + s (s = +5 male / −161 female). That exact model is the important boundary of this page: the headline is the output of this identity and the values entered into its fields. It should not be silently substituted with another equation simply because another website uses a different convention.

For BMR Calculator – Age 30, in this calculator configuration, for the supplied male / 30-year / 170 cm / 70 kg example, the engine reports 1,617.5 kcal/day. A hand check should use the same sex constant, age, height, and weight. If your hand calculation disagrees, check units and the selected sex before assuming the calculator is wrong.

Worked example using the shipped calculator values

  1. Select male for sex.
  2. Enter age as 30 years.
  3. Enter height as 170 cm.

Why this particular BMR configuration is useful

In this calculator configuration, this age-indexed page is useful when the search itself includes a specific age. The age is not a decorative label; it is an explicit input in the equation.

For BMR Calculator – Age 30, in this calculator configuration, for the shipped sample, the calculator reports 1,617.5 kcal/day. The result follows the Mifflin-St Jeor expression Mifflin-St Jeor: 10W + 6.25H − 5A + s (s = +5 male / −161 female). The arithmetic makes the role of age explicit: with the other sample values fixed, each additional year reduces the male-example result by 5 kcal/day. That is a property of this equation, not a claim that every person’s metabolism changes by exactly that amount.

For BMR Calculator – Age 30, in this calculator configuration, compared with the age-29 configuration, the same 170 cm, 70 kg male sample is expected to be 5 kcal/day higher because the age term changes by one year. Compared with the age-31 configuration, the same sample is 5 kcal/day lower because the supplied equation subtracts 5 times age.

For BMR Calculator – Age 30, in this calculator configuration, the practical lesson is to avoid comparing age-specific pages using different body measurements. If height or weight changes at the same time as age, the output reflects all of those changes. For a clean age comparison, hold the other inputs constant and change only the age.

What this page can and cannot establish

For BMR Calculator – Age 30, in this calculator configuration, the calculator can show what the selected equation returns from the values entered. It cannot measure resting metabolism directly, verify a person’s health status, or determine an appropriate calorie intake. The distinction matters because an estimated resting-energy value is not the same thing as a complete daily energy requirement.
