Metric, from the start
Kilograms and centimetres, with no conversions between you and your next step.
Add a meal or a weigh-in. Your records stay on this device until you choose to sync.
Compare formulas, set a pace and turn energy needs into a practical macro target.
Log meals and weigh-ins. Follow a smoother trend, with no pressure to make every day perfect.
Pro uses complete intake records and trend weight to make measured weekly adjustments.
Enter body weight in kilograms and height in centimetres. The Mifflin-St Jeor equation uses these units directly, and BMI uses height in metres squared. A value entered in the wrong unit can change the result dramatically, so this page keeps metric fields fixed and clearly labeled.
Use the same scale, a similar time of day and comparable clothing when tracking weight. You do not need to eliminate ordinary daily fluctuations; the trend curve is designed to smooth them. Your saved records use kilograms internally, so switching display units in the workspace does not change historical measurements.
One shared calculation engine, with a focus that fits your goal.
No. Kilograms and centimetres are the native units of these equations. An imperial input is converted before the same calculation.
Yes. The main calculator and planner support both unit systems while storing measurements consistently in metric units.
