Known limitations

This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
Use the result as a planning estimate unless the calculator page states a stricter purpose.

Assumptions

The estimate uses the Mifflin-St Jeor equation, which is intended for the general adult population.
BMR reflects calories burned at rest, not a full day of normal movement or exercise.
Body composition, illness, and hormonal factors can shift real metabolic needs above or below the estimate.

Unit handling

Gender accepts one of the configured options.
Age accepts values in years.
Height (Ft) accepts numeric values.
Height (In) accepts numeric values.
Weight (lbs) accepts numeric values.
BMR is displayed in kcal/day.

Rounding rules

Number displays use up to 2 decimal places in the calculator UI.
