# Weight Conversion

Our weight conversion calculator can help you find out how many grams are in an ounce or how many pounds are in a ton or just about any other weight conversion you can imagine. If you are constantly having to convert metric units and standard units, it can be almost impossible to remember the values. Because there are two common sets of units for weight, the calculations can be complicated.

For all practical, daily purposes weight can be described as mass, since the gravitational force is fairly constant on Earth. When talking about weight in a scientific context away from the Earth’s gravity, then weight takes on a whole new meaning, which we will steer clear of for our conversion purposes.

Weight measurements date back to 3000-4000 BC, and the “Magna Carta” in 1215 stated that there would be “one measure of wine throughout our whole realm, and one measure of ale and one measure of corn–namely, the London quart…” The International System of Units or SI units is the current standard metric system and has widely been accepted across the globe. This is based on the kilogram and a decimal system of conversion.

A few other countries, including the United States, use the US customary units even though most of them have adopted the metric system. The US customary units include the pound, ounce, ton, etc. and are not based on a decimal system. This causes conversions between these units to be extremely difficult without the use of a calculator.

Since both units of measurement are commonly used, it is important to be able to convert the units of measure quickly and accurately. It is simple to convert 1 kilogram into 1000 grams, but how many grams are in a pound? How many ounces in a kilogram? To use our weight converter simply choose the units you wish to use, and enter the measurement you know. Our calculator will do the computations for you.
