Relative Strength Calculator

Relative Strength Calculator

A 120 kg bench is impressive at 70 kg body weight and ordinary at 110 kg — raw load alone does not tell you how strong you are for your size. Enter the weight you lifted and your body weight, and this calculator returns your relative strength as a ratio and as a multiple of body weight. Use it to compare lifts across athletes, track strength independent of weight changes, or set body-weight-multiple goals for any lift.

Relative strength is the weight you lift divided by your body weight. It lets you compare strength fairly between people of different sizes — a 100 kg squat means very different things at 60 kg and 90 kg body weight. Coaches often quote milestones as multiples of body weight (for example a 2× body-weight deadlift). Use the same lift and consistent body weight to track progress over time.
