What is a Kilogram (kg)?

A kilogram (kg) is the standard unit used to measure mass in the metric system (SI). It’s the most common weight unit worldwide—used in shops, kitchens, shipping, fitness, science, and industry.

In everyday life, you’ll see kilograms used to weigh things like fruit, vegetables, groceries, luggage, and parcels. In technical fields, kg is also used in engineering, manufacturing, and research because it’s reliable and easy to scale up or down.

Kilograms convert smoothly into other metric units:

• 1 kg = 1,000 grams (g)
• 1 kg = 1,000,000 milligrams (mg)
• 1,000 kg = 1 metric ton (t)

Quick conversion tips:

• kg to pounds (lb): multiply by 2.2046
• kg to stones (st): divide by 6.3503

Because stones are usually written as stones + pounds (not decimals), our Weight Converter automatically converts kg into the format people actually use—fast, accurate, and easy to read.

What is a Pound (lb)?

A pound (lb) is a widely used unit of weight in the United States, the United Kingdom, and several other countries. It’s easy to recognise by its symbol, lb, and it’s especially common for everyday measurements.

Here’s the key conversion:

• 1 lb = 0.45359237 kg
• 1 lb = 16 ounces (oz)

People use pounds for all kinds of daily needs—like weighing body weight, food and groceries, packages, and gym equipment. You’ll see it on dumbbells, shipping labels, and nutrition or fitness tracking apps.

Quick conversion tip:

• Lb to kg: divide by 2.2046 (or multiply by 0.4536)
