Estimate calories burned rowing from power output and duration.
Rowing engages more muscle mass than cycling at the same power, which is why it feels harder for a given wattage. The energy calculation is the same, driven by mechanical work and efficiency. Erg monitors report calories using a fixed formula that ignores body weight, so a heavier rower burns more than the display suggests.
Rowing Calories
Energy input = mechanical work ÷ efficiency, converted at 4.184 kJ per kcal
These figures are estimates based on population-average formulas and are intended for training and recreational planning only. They are not medical advice. Consult a qualified health professional before starting or changing an exercise programme, particularly if you have an existing medical condition.
