Cubit units have not been in serious use for at least 1000 years!
About 17 inches...
A cubit is not considered a standard unit in the International System of Units (SI) because it is not a fixed and universally accepted measurement. The length of a cubit can vary depending on the culture and time period in which it is used, making it an imprecise and inconsistent measurement. Modern standards prefer precise and standardized units for universal usage and comparison.
Some units include the "hand" (horses) and the "span" (great span) originally equal to half of a Roman cubit.
The ancient Egyptian units of measurement were called cubit, palm, and digit. These units were used to measure length in ancient Egypt.
