From 5Kg Milestones to World Records: How Metric Lifting Weights Drive Strength Sports
By Marcus Vance
Q1: What is the exact formula to convert 5kg to lb?
A1: Multiply the mass in kilograms by the international avoirdupois constant of 2.20462. For 5kg, the calculation is 5 × 2.20462 = 11.0231 pounds.
Q2: Why do powerlifting and weightlifting federations use kilograms instead of pounds?
A2: Kilograms serve as the international scientific standard under the International System of Units (SI). Using metric units guarantees identical competition standards worldwide, eliminating the variations found in commercial imperial equipment.
Q3: How much weight is added to a barbell when adding a 5kg plate to each side?
A3: Adding one 5kg plate to each sleeve increases the total load by 10 kilograms, which equals exactly 22.0462 pounds (commonly rounded to 22.05 lbs on platform scoreboards).
