Our free online unit converter tool helps you convert between length, weight, temperature and other measurements with high precision. All calculations are performed securely in your browser without any server uploads. Perfect for students, engineers, and professionals who need quick, accurate unit conversions.
You can convert between kilograms, grams, milligrams, pounds, and ounces. The converter supports both metric (SI) and imperial/US customary weight units.
Our weight conversions use precise conversion factors. For example, 1 kilogram is exactly 2.20462262185 pounds. We maintain high precision to ensure accuracy in scientific and technical conversions.
The metric system (kilograms, grams) is used worldwide and in scientific contexts. The imperial system (pounds, ounces) is common in the US. Medical and scientific measurements typically use metric units.
Mass (measured in kg) is the amount of matter in an object and doesn't change with location. Weight (measured in N) is the force of gravity on an object and varies with location. In everyday use, we often use these terms interchangeably.
1 pound equals 16 ounces. Our converter handles this automatically, but it's a useful reference for quick mental calculations. For example, 1.5 pounds is 24 ounces.
Milligrams are useful for very precise measurements, commonly used in medicine, chemistry, and nutrition. 1 gram = 1000 milligrams, providing better precision for small quantities.
