Measure how much cycling, sprint-test, or jump-test power you produce for each kilogram of body mass. Relative power can be more informative than watts alone when comparing your own tests over time, especially after a strength block or body-mass change. Compare only tests performed with the same device and protocol.
Power-to-weight ratio = power in watts ÷ body mass in kilograms.
A higher ratio means more measured power relative to mass. It does not by itself measure soccer skill, acceleration technique, repeatability, or endurance.
Do not compare peak power from one testing method with average power from another.
A player producing 900 W at 75 kg has a power-to-weight ratio of 12.0 W/kg. At 72 kg, 864 W would preserve that ratio.
It can support acceleration and jumping, but soccer performance also depends on technique, repeat efforts, endurance, and decision-making.
Enter kilograms; the calculator separately reports watts per pound.
Either can be useful, but comparisons must use the same metric and test protocol.
It shows the wattage required to preserve the current ratio at the comparison mass.
Only if power is maintained. Weight loss that reduces power may leave the ratio unchanged or worse.
