Understanding Pounds and Kilograms
Pounds (lbs) are the imperial unit of weight, used primarily in the USA. Kilograms (kg) are the metric unit, used in most countries worldwide. The conversion factor is fixed: 1 pound equals exactly 0.453592 kilograms, which means 1 kilogram equals approximately 2.20462 pounds.
When You'll Use This Conversion
Common situations: Reading US product listings while living abroad, converting fitness/gym weights from pounds to kilograms, checking package limits for international shipping, converting health/medical measurements, reading US recipe weights.
Why it matters: Most of the world uses kilograms, but the USA uses pounds. Understanding both systems helps when working with international products, recipes, or fitness data.

Frequently Asked Questions
US product specs are in pounds — how do I match them to European kg sizes?
Divide the pound value by 2.205 to get kg. A 10 lb bag = 4.54 kg, a 25 lb bag = 11.34 kg. European equivalents often come in rounded metric sizes (5 kg, 10 kg) that don't match exactly. When buying, round up to the nearest available metric size to avoid running short.
A US recipe says 2 lbs of chicken — what does that look like at the supermarket?
2 lbs = 907 g, so look for a roughly 900 g pack. Supermarket packs are typically 500 g, 750 g or 1 kg. A 900 g or 1 kg pack is the closest match. For 1 lb, look for a 450 g or 500 g pack.
What are the parcel weight limits in pounds vs kg for major carriers?
USPS domestic: up to 70 lbs (31.75 kg). FedEx and UPS Ground standard: up to 150 lbs (68 kg). International parcels: typically capped at 30 kg (66 lbs) by customs rules, though carrier limits may be higher. Always check the destination country's customs limit, not just the carrier's.
Dumbbell and weight plate labels are in lbs — how do I convert to kg?
5 lbs = 2.27 kg, 10 lbs = 4.54 kg, 25 lbs = 11.34 kg, 45 lbs = 20.41 kg. Most European gym equipment uses kg plates (2.5, 5, 10, 20 kg). A 45 lb "bar standard" in the US is closest to a 20 kg plate in Europe. Use exact values when programming strength training to avoid overshoot.
Is 200 lbs considered heavy?
200 lbs = 90.72 kg. Context depends on height: at 5'10" (178 cm) this gives a BMI of ~28.8 (overweight range); at 6'3" (191 cm) it gives ~25.1 (healthy range). Weight alone is not a health indicator without height and muscle mass. Use a BMI calculator for a more complete picture.
