Kilograms to Pounds (kg to lbs) Converter
Convert between kilograms and pounds with precise conversion factor. Both directions supported with adjustable decimal precision for clinical accuracy.
How Weight Conversion Works
The kilogram (kg) is the SI standard unit of mass used in most countries. The pound (lb) is the imperial unit used primarily in the United States, UK (alongside stones), and some other countries. The conversion between them uses the internationally defined factor: 1 kg = 2.20462 lbs. This precise ratio ensures accuracy for clinical calculations, especially in dose calculations based on weight (e.g., mg/kg).
Formulas
Worked Examples
Example 1: Convert 70 kg to lbs (typical adult male)
lbs = 70 × 2.20462
lbs = 154.3
Example 2: Convert 150 lbs to kg (patient weight in hospital)
kg = 150 ÷ 2.20462
kg = 68.0
Example 3: Convert 25 kg to lbs (paediatric patient)
lbs = 25 × 2.20462
lbs = 55.1
When This Converter Is Used
- •Converting patient weight for medication dosing (especially mg/kg calculations)
- •International patient transfers between metric and imperial systems
- •Paediatric dosing calculations where weight-based accuracy is critical
Clinical safety note: Always use current, accurate patient weight. For critical medications, verify the conversion and have another provider confirm before administration.
