nondecimalised
Nondecimalised refers to a system or measurement that has not been converted to or operates using a base-ten, or decimal, system. This term is often used in the context of historical measurements, currency, or counting systems that predated the widespread adoption of decimalization. For example, before the introduction of decimal currency in many countries, systems of pounds, shillings, and pence were common. These systems were not based on powers of ten and thus would be considered nondecimalised. Similarly, older systems of weights and measures, such as feet and inches, or bushels and pecks, are also nondecimalised when contrasted with metric units like meters and kilograms. The process of decimalisation involves reexpressing these nondecimalised quantities in a base-ten format for easier calculation and standardization. The term highlights the contrast between traditional, often more complex, numerical arrangements and the simplicity and universality offered by the decimal system.
