Rowing Calorie Burn Calculator

The rowing calorie burn calculator estimates total energy expenditure during an ergometer workout, providing a more accurate figure than the Concept2 monitor alone. The Concept2 calculates displayed calories purely from mechanical power output using the formula: Cal/hr = Watts × 4.2, which assumes a standardised body and does not account for individual body weight, metabolic rate, or mechanical efficiency. In reality, human mechanical efficiency on a rower is approximately 20-25%, meaning actual metabolic cost is 4-5 times the mechanical work displayed. A 90 kg rower burns significantly more total calories than a 60 kg rower at the same wattage, a distinction the Concept2 display does not capture.
