However, it's important to note that "hemi-" is rarely used in the context of standard metric units.
For example, you wouldn't say "hemi-meter" to refer to half a meter. You would simply say "half a meter" or use a decimal notation like "0.5 meters".
The "hemi-" prefix is more commonly used in scientific and technical contexts for describing things that are half of a particular unit. For instance, "hemisphere" refers to half of a sphere.
