About these units
Millimeter (mm)
A millimeter is one-thousandth of a meter and is used extensively in fields that require fine control and precision. Engineers and machinists frequently rely on millimeters in technical drawings and machining specifications, since the unit supports very precise tolerances without resorting to decimals. In construction, millimeters provide clarity for component dimensions, door and window fittings, and joinery work. Millimeters are also critical in medical imaging (such as CT or MRI slice thickness), entomology, electronics, and automotive design. Many mechanical failures or malfunctions arise from deviations of only a few millimeters—highlighting the importance of precision. On a more everyday level, rainfall measurements and snow depth reports often use millimeters for accuracy.
Long Cubit (long cubit)
The long cubit is an extended form of the traditional cubit, often adding an extra palm or handbreadth, resulting in a measurement of approximately 0.525 meters. It was used in ancient Egypt, Israel, and surrounding regions for larger construction projects. This unit allowed architects to scale up structures while maintaining proportionality, particularly in monumental architecture like temples, palaces, and pyramids. Its standardized use enabled consistency across multiple teams of builders working simultaneously on expansive projects. The long cubit also appears in historical and religious texts, giving scholars a reference for interpreting ancient measurements and architectural descriptions.
