FAQ

Nigeria officially uses the metric system, but imperial units persist in many sectors due to British colonial heritage. Land surveys often use feet and chains; fabric and tailoring use yards; some construction still uses inches for pipes and screws. Urban planners, SURCON surveyors, and government documentation increasingly use metric (metres, hectares) but field workers often work in feet.
A standard Nigerian plot is 100 × 100 feet = 10,000 square feet = approximately 929 square metres. However, plot sizes vary by state: Lagos standard plot is often 60 × 120 feet (about 669 sqm), while Abuja FCT uses 450 sqm as a standard unit. Always confirm the actual survey dimensions on the Certificate of Occupancy (C of O).
1 metre = 1.0936 yards. They are very close in size — a metre is about 9.4 cm longer than a yard. For fabric purchases at Nigerian markets, 1 yard of fabric is approximately 91.4 cm. When markets quote "6 yards" (e.g. for aso-ebi), that is about 5.49 metres.
