in Jamaica refers to the legally recognised framework of units, standards, instruments, and regulatory practices used to quantify physical quantities such as length, area, volume, mass, and time across commerce, construction, land administration, science, and daily life. It encompasses both the International System of Units (SI), which is the official standard, and a range of historical and customary units that remain embedded in practice, particularly in real estate and construction.
In Jamaica, the measurement system is not merely technical. It sits at the intersection of law, trade, property rights, and development, influencing how land is defined, how buildings are constructed, how goods are sold, and how value is assessed.
