Work through the task
Inspect the arithmetic of the stated adult resting-energy equation.
- Select the equation coefficient and enter age, height and weight using the labelled units and permitted ranges.
- Read the equation estimate as an estimate. Changing the coefficient changes the calculation; this page does not choose a personal health target.
- Review the result before copying or downloading. Editing an input invalidates the previous result; keep an original if the transformation matters.
Example to check
Hypothetical input: 70 kg, 175 cm, age 30, Male coefficient (+5). The arithmetic 10×70 + 6.25×175 − 5×30 + 5 gives 1,648.75 kcal/day estimated resting energy. This is not a daily intake target.
Limits and output behavior
Use finite values within the bounds shown by the controls. This calculator uses floating-point arithmetic and rounded display values; an exported decimal is not a promise of exact accounting precision. The supported equation and adult input ranges are shown in the form. It does not model an individual’s medical circumstances.
Troubleshooting
Complete all four fields, including the equation coefficient. Check the stated adult age, height and weight bounds rather than entering a missing value as zero.
Questions
Is the displayed estimate a daily intake target?
No. It is the arithmetic result of the selected resting-energy equation for the supplied bounded inputs. It does not set a personal intake or treatment target.
