Translate rowing pace into estimated flywheel power and compare that output with body mass. Along with watts per kilogram, the calculator reports 500-meter pace, total mechanical work, and average force-equivalent per stroke. It is most useful for tracking one athlete over time because erg power-to-weight is not a complete measure of on-water speed.
The power estimate follows the common Concept2 pace relationship. Work per stroke is a session average and does not describe peak handle force.
This calculator is an estimate for training and planning. It does not diagnose readiness, injury, or medical recovery.
At 2:00/500 m, estimated power is 203 W. At 75 kg that is 2.71 W/kg; for 20 minutes at 28 spm, average work is about 435 joules per stroke.
Compare results only when the input method and relevant conditions are similar. Changing distance, exercise, equipment, or reference values can change what the number means.
Use a representative average for the completed work. If the variation is large, calculate separate blocks and compare them instead of hiding the variation in one average.
Only the factors shown in the input panel are included. Use the interpretation as a planning aid and add context from conditions, technique, sleep, soreness, and recent training.
Body mass, reference performance, training history, and the purpose of the session affect how a result should be used. The calculator does not assign a universal athlete grade.
Update a reference after a representative test or a meaningful fitness change. Keeping it stable for several sessions makes trend comparisons easier to interpret.
