a measurable extent of some kind, such as length, breadth, depth, or height
Pounds are a unit of weight and centimeters are a unit of length. We can't convert one to the other. Something that weighs 160 lbs will have dimensions, but the dimensions of 160 pounds of lead will be vastly different from the dimensions of 160 pounds of feathers.
The metric unit of volume is meter squared: m3.
The millimeter is a unit of length. The liter is a unit of volume. The two units of measure can not be equated.
You can't just convert any unit to any other unit. The units must be of a compatible type. Thus, you can convert a unit of length to another unit of length, a unit of area to another unit of area, or a unit of volume to another unit of volume.
Yes. A meter is a unit of length (1 dimension), a square meter is a unit of area (2 dimensions).
No, length is not always larger than area. Length is a one-dimensional measurement, while area is a two-dimensional measurement. For example, in a square with sides of length 1 unit, the length is 1 unit, but the area is 1 square unit. In many cases, especially with larger dimensions, area can easily exceed length.
Cubic meter is a unit for volume, which requires 3 dimensions, length, width, height. Knowing the length of an object is useless unless you have the other two dimensions.
Length is one of the dimensions. Length, width, height etc. which can describe an object are called its dimensions.
Volume has three dimensions. It has a cubic unit (or written as a unit cubed), eg a cubic centimetre. The metric volume unit of a litre is the same as 1,000 cubic centimetres.
I don't know what you mean by a cubic tonne - a tonne is a measure of mass/weight and it makes no sense to give it two or more dimensions, unlike a length (which has one dimension), an area (which has two dimensions, and for a rectangle is a length times another length to give a square unit), or a volume (which has three dimensions, and for a cuboid is a length times another length times another length to give a cubic unit). Density is in a mass unit divided by a cubic unit, eg it could have units of "tonnes per cubic metre". ------------------------------------------------------ Assuming you meant: What is 200000 tonnes in pounds, then: 1 kg ≈ 2.205 lb 1 tonne = 1000 kg ≈ 1000 × 2.205 lb = 2205 lb → 200,000 tonnes ≈ 200,000 × 2205 lb = 441,000,000 lb
