What is weight

Weight is measured using a scale

Weight is an object's relative mass and the force of gravity on an object. NASA explains that weight is the force generated by the gravitational attraction of the earth. Because the weight of an object is really the force of gravity on it, the weight of an object will be the same everywhere on Earth, but in space objects are weightless and the weight of an object on another planet with a different gravitational force will be different.

Scales are instruments that measure weight and vary in size from fitting into your pocket to being larger than a semi truck. Common measures of weight are tons, pounds, ounces, and grams. Tons, pounds, and ounces are imperial units of weight, and grams are metric units of weight. A ton is 2,000 pounds and a pound is 16 ounces. To convert between different measures of weight, including imperial and metric weight units, use the unit conversion tools above. The table below compares common units of weight.
