Mass And Weight Converter
Mass And Weight Converter is online conversion calculator that allows you to convert units of weight/mass between various measurement systems. You can easily convert kilograms to pounds, pounds to ounces, metric tonnes to pounds, long tons to short tons, pounds to kilograms etc. You can easily check carat weight in grams or grains. It supports atomic masses also (such as 'Atomic Mass Unit', MeV/c2,Planck Mass). Our examples show you how to calculate kilograms vs pounds (pounds vs kilograms) and give you fast access to some interesting weights and masses (e.g. the biggest diamond carat weight).

Carbon C12 Mass
Carbon isotop C12 contains 6 neutrons and 6 protons. Its mass is used as a base to define an Atomic Mass Unit and its 12u by definition. (Earlier Atomic Mass Unit was defined as 1/16 of O16)

Mass of the planet Jupiter
Jupiter Mass is widely used in astronomy to describe masses of other planets, gas giants and extrasolar planets. Jupiter Mass is approximately equal 1.8986 × 1027 kg or 4.1857 × 1027 pounds The Jupiter was choosen as a base because it is the largest planet in our solar system.

Cullinan Diamond Mass
The Cullinan Diamond is the largest diamond ever found. Its mass was 3106.75 ca (carats) (621.35 grams, 1.3698 pounds). The famous Koh-i-noor diamond weights 'only' 105 ca (21 grams, 0.0463 pounds) The stone was found in Cullinan, Gauteng, South Africa, on January 25, 1905 by Frederick Wells. It was divided into 9 large and 96 smaller stones by Joseph Asscher. The largest part named 'Great Star of Africa' or Cullinan I weights 530.2 ca.

Kilogram vs. Pound Example
If your weight or mass is given in kilograms and you want to know pound weight/mass, you should type quantity of kilograms in the edit box labeled 'kilogram'. You will get pound weight in the edit box labeled 'pound [lb]'. On the other hand, if you want to know kilogram weight (or tonne, long ton, stone, carat weight) of any substance/item knowing how many pounds it weights, simply type the pound weight into the edit box labeled 'pound [lb]' and the system will give you an answer.
