To convert lbm (pound-mass) to lbf (pound-force) for an object located at the Earth's surface, multiply the mass (in pounds) by the "standard gravitational force" of 32.174049 (typically rounded to 32.174) to calculate lbf. If the object is not located at the Earth's surface, a different ratio must be used.Continue Reading
Find the mass of the object in question in pounds, assuming that this is an object at Earth's surface.
If the object is located at the Earth's surface, multiply the mass by the "standard gravitational force" of 32.174.
After multiplying Step 1 and Step 2, the answer is the lbf, the "pound-force" measured in foot-pound per second-squared.
An lbm is a unit of mass called a "pound-mass." An lbf is a unit of force called a "pound-force." Colloquially, people speak of a pound as if it is unit of mass, but an object weighs varied amounts in pounds depending on the strength of gravity at a given location. For example, a rock that weighs a pound on Earth's surface weighs less on the moon due to lower gravity. However, the mass of the rock would remain the same.
Spring scales measure the magnitude of forces, most commonly weight, which is the downward force of gravity on an object. It works from the principle laid down by Isaac Newton in his third law of universal motion, that for every action there is an equal and opposite reaction.Full Answer >
The difference between compression and tension is that a compressing force causes an object to shorten in the direction of the force, while a tension force causes an object to lengthen in the direction of the force. Regardless of the strength of the material, compression and tension forces always cause some amount of deformation. Different materials deform in different amounts and return to their previous shape differently as well.Full Answer >
A newton is the amount of force required to accelerate 1 kilogram of mass at a rate of 1 meter per second, according to Dictionary.com. In the International System of Units, the newton is abbreviated "N".Full Answer >
In terms of grams alone, the equivalent value of 1 newton cannot be explicitly determined because grams are units of mass while newtons are units of force. However, newtons can be expressed in terms of gram-force.Full Answer >
