How do I convert kg to lbs?

One kilogram equals 2.20462 pounds. To convert, multiply your kg value by 2.205. So 70 kg is about 154.3 lbs, and 100 kg is about 220.5 lbs. To go the other way, divide pounds by 2.205. The converter handles this automatically — just type your value, select kg as the source and lbs as the target, and the result appears instantly.

What is stone, and how do I convert it to kilograms?

Stone is a unit of body weight used primarily in the UK and Ireland. One stone equals exactly 14 pounds, or 6.35029 kilograms. So if someone says they weigh 11 stone, that's 154 pounds or about 69.9 kg. If you're used to kilograms and encounter a weight given in stone, the converter handles it directly — select stone as your source unit and kilograms as the target.

Can I use this for luggage weight limits?

Yes — this is one of the most practical uses. Airlines list baggage allowances in either kilograms (most international airlines) or pounds (many US carriers). A typical economy allowance is 23 kg, which is just over 50 lbs. If your bag is showing one unit on your bathroom scale and the airline specifies another, enter the reading and convert it before you head to the airport — no surprises at check-in.

What is the difference between weight and mass?

Mass is the amount of matter in an object — it stays the same wherever you are. Weight is the force gravity exerts on that mass — it would be different on the Moon. In everyday life the distinction doesn't matter: when you say something weighs 5 kg, you mean its mass is 5 kg. In physics and engineering, the difference is significant. This converter works for both mass units (kg, grams) and the weight units people use daily (lbs, ounces, stone).

Solving Mass Metric Discrepancies

The recipe is in ounces. Your scale is in grams. The airline says 23 kg but your bathroom scale shows pounds. Your gym app tracks in kilograms but the dumbbells are labeled in lbs. Weight units are one of those small mismatches that come up constantly — in the kitchen, at the airport, on the gym floor, and in science class — and the mental math to fix it never quite sticks.

This weight converter handles kilograms, pounds, grams, ounces, milligrams, stone, and more — covering metric, imperial, and the units that don't fit neatly into either. Type your value, pick your units, and get your answer instantly. It runs 100% in your browser with no sign-up and nothing sent to any server.

Real-World Case

"Scaling Transatlantic Bread Recipes Flawlessly"

Tom, a home cook in Toronto, recently started following a UK food blog for its bread recipes. Every recipe listed flour, water, and salt in grams — straightforward — but butter in ounces, because the author apparently scaled the recipe from an older American source. Tom's scale does grams only. Rather than hunting for a unit-specific converter or doing the math on paper, he opened the Utilx weight converter, typed each butter amount, switched ounces → grams, and jotted the results in the recipe margin. Four conversions, under a minute. The loaf turned out right.

One ounce equals 28.3495 grams — typically rounded to 28.35g for cooking purposes. So 2 ounces is about 56.7g, and 4 ounces (a quarter pound) is about 113.4g. If a recipe calls for ounces and your kitchen scale is in grams, multiply the ounce amount by 28.35 or just enter it into the converter for an instant result.
