scale and balace
A pound is a measure of mass, a kN is a measure of weight. The two are measures of different things and a direct conversion is not valid.
Mass and weight are two different things. It does not make sense to ask which is more accurate. Mass is used to measure an object's ability to resist a force. f = ma, or m = f/a. Weight is used to measure an object's force applied due to gravity. Measured in newtons, f = ma, or newtons = kilograms time 9.81 meters per second squared.
centimeters measure length. grams measure weight. the two are not interchangable
You do not. A gram is a measure of mass, whereas a kilometre is a measure of distance. The two measure different things and, according to the basic principles of dimensional analysis, conversion from one to the other is not valid.
Grams is a measure of weight, kilometres is a measure of distance, the two do not compare.
Mass and weight are two different things: you cannot measure the mass of your weight. That is like talking about the temperature of your height - it makes no sense.
Newton (SI) and pound-weight (Imperial).
These two things can not be compared in this fashion because grams is a measure of weight, and meters are a measure of length.
You can't compare WEIGHT with MASS - those two are used to measure quite different things. It doesn't make sense to say that they are the same, or that they are different. You can only compare mass with mass, or weight with weight.
Mass/Weight Volume Density Hardness (and more)
A pound is a measure of mass, a kN is a measure of weight. The two are measures of different things and a direct conversion is not valid.
None. An erg is a measure of energy while a gram weight is a measure of force. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.
The two units are mass and weight and I can't answer the equal amount
You don't. Pascals is used to measure pressure, centigrade is used to measure temperature. Those two are completely different things.
Temperature & Height
You can't. One is a measure of weight/mass, the other is a measure of area.
There can be no equivalence. 5'1" is a measure of length or distance in 1-dimensional space while a weight is a measure of force. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.
