Weight=mass x acceleration due to gravity = mass(lbs) x 32.1 (ft/s^2)

So, mass(lbs) = (weight)/(32.1)

Multiply the mass fraction by 100.

"Pound" is a unit of force. "Kg" is a unit of mass. They don't convert directly. On Earth, 70 pounds is the weight of 31.751 kg of mass. (rounded) On the moon, 70 pounds is the weight of 191.858 kg of mass. (rounded) In other places, 70 pounds is the weight of different amounts of mass.

You cannot. Volume and weight are two different characteristics and, according to basic dimensional analysis, conversion from one to the other is not valid. If you had the density of the substance, you would be able to convert the volume to mass. But mass is not the same as weight. You would then need information about the strength of gravitational attraction at the location to convert the mass into weight.

You can't convert the two. One is measurement of weight, and the other is a measurement of mass.

Usually a scale. Get the weight and convert to mass.

To convert mass to weight, you need to multiply the mass by the acceleration due to gravity. The formula is weight = mass x gravity. Gravity is typically 9.81 m/s^2 on Earth.

Basically you need more information. You can use the following formulae: density = mass / volume weight = mass x gravity

cc (cubic centimeters) is volume gms (grams) is mass (or weight) They don't convert.

You never can convert centimeters to grams. A length has no weight. Essentially correct, but just to be pedantically accurate, a gram is a unit of mass, not weight.

To convert mass to weight in Newtons, you can use the formula: Weight (N) = mass (kg) x acceleration due to gravity (m/s^2). The acceleration due to gravity on Earth is approximately 9.81 m/s^2. Simply multiply the mass in kilograms by 9.81 to get the weight in Newtons.

To convert force into weight, you multiply the force by the acceleration due to gravity. Weight is a measure of the force of gravity acting on an object. The formula to calculate weight is weight = mass x acceleration due to gravity.
