• Commonly used worldwide for measuring small quantities, such as food ingredients, medication doses, and scientific samples.
• One kilogram equals 1,000 grams.

What Is a Pound?

• The pound (lb) is a traditional imperial unit of weight.
• Widely used in the United States, United Kingdom, and some other countries.
• Often used for measuring body weight, food packages, and other commodities.
• The pound has several definitions, but the most common is the avoirdupois pound, which equals exactly 16 ounces or approximately 0.45359237 kilograms.

How to Convert 249 Grams to Pounds
