Worked Examples
Gym Weight Conversion
An athlete following a European training program needs to deadlift 120 kg at a US gym. Converting: 120 x 2.20462 = 264.6 lbs. Using standard 45 lb plates, this is a 45 lb bar plus two 45 lb plates and two 25 lb plates per side (45 + 90 + 50 + 90 + 50 = wait, recalculating: bar 45 + 4x45 + 2x25 = 45 + 180 + 50 = 275 lbs). The closest loadable weight would be 265 lbs using smaller plates.
Baby Weight at Pediatrician
A baby weighs 4.2 kg at birth. Converting: 4.2 x 2.20462 = 9.26 lbs, or 9 pounds 4 ounces. In the US, baby weights are announced in pounds and ounces. To get ounces, take the decimal portion (0.26 lbs) and multiply by 16 = 4.16 ounces. Average newborn weight is 3.0-4.0 kg (6.6-8.8 lbs).
