Units that are equivalent to numbers (have dimensionality 0), such as mega or degree, are converted to numbers. When height would be unclear—for example if the figure is not “level” —people cannot know what is meant by width, depth, or height without labels, although length is generally still assumed to refer to the longest measurement on the figure. The base unit of length in the SI system is the metre.This has had several definitions over time: 1889 The International Bureau of Weights and Measures defines the metre as the distance between two marks on a platinum-iridium alloy bar (the International Prototype Metre).This prototype is kept in a vault in Sèvres, near Paris. A millimeter is about the thickness of a plastic id card (or credit card). We can use a simple ruler and measure length. And, as in two dimensions, terms like “length,” “width,” and “height” won’t feel natural or be clear for some shapes, like a tennis ball. For example, the metre is a standard unit to measure length.
