No. But you can multiply the length of something by the mass of a unit of length of that same something provided it is of uniform cross section. eg if a one meter length of wire ways 7 grams, a kilometer length of that wire will weigh 1000*7 grams.
No. In general, you can only convert units that measure the same thing: thus, you can convert length to length, area to area, mass to mass, etc.
The mass of a pendulum does not affect its period of oscillation. The period of a pendulum is determined by its length and the acceleration due to gravity. This means that pendulums with different masses but the same length will have the same period of oscillation.
These are not the same dimensions. Tonnes per sec --> Mass / time. MPa --> Force/area --> [Mass * Length / (time)2 ] / [Length2] --> Mass / [time2 * length]
No. Mass is what things are made of. Area is a way to how much length and width is covered by one of an objects sides.
No. "Metric" refers to a system of measurement - of mass, length, volume etc. Tonne is a unit for measuring mass.
It doesn't make sense to convert that. In general, you can only convert between units that measure the same thing - length to length, area to area, mass to mass, etc.
Kilogram is a unit of mass, not of length.Kilogram is a unit of mass, not of length.Kilogram is a unit of mass, not of length.Kilogram is a unit of mass, not of length.
Length and volume are not the same, any more than time and mass are the same. They are different properties that are measured with different units.A cube that has a height and length and width of one unit will have a volume of one cubic unit, but that does not mean that it is correct to say that its length and volume are the same. Saying that is like saying that an hour weighs the same as a kilogram.
The frequency of a pendulum is not affected by its mass. The frequency is determined by the length of the pendulum and the acceleration due to gravity. A more massive pendulum will swing at the same frequency as a less massive one if they have the same length.
You can't compare that. You can only compare units that measure the same kind of thing: length with length, volume with volume, mass with mass, etc.
It doesn't make sense to convert that. In general, you can only convert between units that measure the same type of thing: you can convert length to length, time to time, mass to mass, etc.
