Yarn is usually measured in yards or meters, regardless of its origin.

That roll of carpet has the square yardage of its width measured in yards multiplied by its length measured in yards. You may need to unroll it to find the length exactly, or if you are only looking for an approximate area and hence length, you can assume the roll is made up of concentric rings of carpet, measure the diameter of each ring from the inside to the outside (to the backing of the carpet) and use these find the circumference of each ring and sum them - this sum can be calculated by summing the diameters and multiplying that sum by π. The last ring will not usually not be a full ring, so it can either be measured directly or added in as a fraction of the whole ring multiplied by its diameter.
D.M.M = Dyed Metric Measurement. Means yarn count being measured after dying yarn. Cheers - Trevin Alles
The diameter is measured using a tape measure.
Diameter.
In the US its diameter is measured in inches.
A diameter is measured by using a ruler. However, you also could use a digital caliper to measure the diameter of a circle.
Tube is measured by outside diameter, pipe is measured by inside diameter.
Depends on the material of the yarn, diameter, etc.
Cells are typically measured in micrometers
The diameter of the bullet casing, measured at 7.3 mm, is 7.3 millimeters.
