What is the difference between mass and volume? On Earth, gravitational acceleration can vary by as much as 0.5%, changing with distance from the Earth's core, as well as latitudinally.ġ4. Mass is measured in grams, kilograms and, tonnes (Metric) or ounces and pounds (US units).Ī scale can't measure mass directly, because the weighing mechanism and the weight of any given object are dependent on local gravity. But weight is caused by gravity, so your weight on the Moon is less than here on Earth, while the mass stays the same. Mass is commonly measured by how much something weighs. If you're measuring the mass of an object on Earth, divide the weight in Newtons by the acceleration of gravity on Earth (9.8 meters/second2) to get mass.Ī measure of how much matter is in an object. You'll need to convert the weight units to Newtons. This will happen when an object is at the centre of earth, as g=0 at centre of earth, so weight will be 0 while mass will always be constant everywhere.ĭivide the object's weight by the acceleration of gravity to find the mass. Mass is the total matter in a body, while weight is the force by which the body is attracted. Yes, a body can have mass but zero weight. For example, an object with a mass of one kilogram has a weight of about 9.8 newtons on the surface of the Earth, and about one-sixth as much on the Moon. The unit of measurement for weight is that of force, which in the International System of Units (SI) is the newton. In scientific contexts, mass is the amount of "matter" in an object (though "matter" may be difficult to define), whereas weight is the force exerted on an object by gravity.ġ kilogram or kilogram-force (kg or kgf) = 9.80665 newtons (N) = 35.2739619 ounces (oz) = 1000 grams (g) = 1000000 milligrams (mg) = 2.20462262 pounds (lbs) = 0.157473044 stones (st). In common usage, the mass of an object is often referred to as its weight, though these are in fact different concepts and quantities. A scale can't measure mass directly, because the weighing mechanism and the weight of any given object are dependent on local gravity. Scales measure weight, which is the force acting on a mass that is equal to the object's mass times its acceleration due to gravity. Tare is the weight of packaging or a container without the goods. Nett Weight is the weight, or mass, of the goods themselves without any packaging. Gross Weight is the total weight of a shipment of goods, including their packaging such as crates, pallets etc. What are the net weight and gross weight? To change from weight to mass divide by gravity (9.8 m/s^2).ġ kilogram (kg) is equal to 2.20462262185 pounds (lbs).ĥ.
#Weight converter kilos to lbs how to
How to convert weight to Mass on a calculator?įw = m * 9.8 m/s^2. You can view more details on each measurement unit: kg or lb The SI base unit for mass is the kilogram.
We assume you are converting between kilogram and pound. For example, to convert 2 kg to lbs, multiply 2 by 2.2046226218, which makes 4.4092 lbs is 2 kg. To convert kilograms to pounds, multiply the kilogram value by 2.2046226218.
