The Department of Consumer Affairs has issued an advisory clarifying that standard SI units will remain the legally recognized units of measurement under the Legal Metrology framework. While customary units may still be used as supplementary references, SI units must be clearly displayed, take precedence, and not create any confusion. This balanced approach promotes transparency, facilitates trade, ensures regulatory compliance, and upholds uniformity in measurement standards.
The Department of Consumer Affairs has clarified that, under the Legal Metrology Act, 2009, standard SI units (International system of units) will remain the legally recognized system for all transactions, compliance, and consumer protection. However, customary units such as inches, feet, or dozen may be used as supplementary information to aid understanding and commercial convenience.
This is permitted only if SI units are prominently displayed, remain the primary reference, and take precedence in case of disputes. Supplementary units must not replace SI units or create confusion or ambiguity.
The advisory aims to balance regulatory uniformity with practical market usage, supporting trade ease and consumer comprehension. All stakeholders, including manufacturers, importer and dealers, must ensure mandatory declarations are made in SI units, with any customary units presented only as clear, non-misleading additional information.
