t = 2 × √(2h / 9.81) with h in metres. Peak power uses the Sayers equation, 60.7 × jump height (cm) + 45.3 × body mass (kg) − 2055. Percentile bands are rough guides for the athlete group you pick, not a lab ranking.
Height measurements convert using the exact standard factors (1 inch = 2.54 cm, 1 metre = 39.3701 inches), so you can enter your jump height or reach in whichever unit you measured it in.
Hang time is calculated from the physics of a vertical jump's round trip: t = 2 × √(2h / 9.81), where h is your jump height in metres — this is the same equation used to estimate airtime from jump height in sports science.
Peak power uses the Sayers equation (60.7 × jump height in cm + 45.3 × body mass in kg − 2055), which is widely used in sports science. Percentile bands compare your jump with typical results for the athlete group you pick — rough guides, not a personalised assessment from a sports lab.
Using the standard projectile-motion formula t = 2 × √(2h / 9.81), where h is your jump height in metres and 9.81 is gravitational acceleration — this models the time spent airborne on a vertical jump's rise and fall.
Peak leg power during the jump, from the Sayers equation: 60.7 × jump height in cm + 45.3 × body mass in kg − 2055. It was built from force-plate tests, so it's a good estimate for tracking progress, but not a lab measurement. Enter your body weight to see it.
They compare your jump with typical results for the athlete group you choose (high-school, college, professional or masters athletes 35+), by sex. They are rough guides for context, not a ranking from an athletic testing lab or a general-population norm.
Yes — height and reach convert using the exact standard factors (1 inch = 2.54 cm), so you can use whichever units you measured in.
