Estimate adult resting energy and daily maintenance needs with metric or US measurements.
For age 30, male coefficient, 175 cm, 70 kg and a 1.2 activity multiplier: resting energy = 1,648.75 kcal/day; estimated maintenance = 1,978.5 kcal/day. Rounded display values are not a precise nutritional requirement.

Resting energy (kcal/day) = 10 × weight in kg + 6.25 × height in cm − 5 × age in years + coefficient. The male coefficient is +5; the female coefficient is −161. Estimated maintenance = resting energy × your selected activity multiplier. Kilojoules = kcal × 4.184.
Activity labels are broad assumptions. Small input differences and day-to-day variation change the result; this is not a measurement of metabolism. It does not account for pregnancy, breastfeeding, illness, medications or individual body composition.

No. It combines a population-based resting-energy equation with a chosen activity multiplier. Actual energy needs vary, and the multiplier is an assumption, not a measurement.
Children, pregnant or breastfeeding people, and people needing clinical nutrition or eating-disorder support should use individualized professional guidance instead.
The published equation has two statistical coefficients. They do not account for individual body composition or every person’s physiology; discuss an appropriate approach with a clinician if uncertain.
No. Re-enter height and weight in the selected units. US height is total inches, not feet.
