4 mm² converts to 12 AWG by cross-sectional area. 12 AWG is 3.31 mm², which is 17% less copper. This is the size where the two systems align worst, and there is no comfortable answer. Neither candidate fits well Gauge Cross-section Against 4 mm² Closest by area 12 AWG 3.31 mm² 17% less Safe substitute 10 AWG 5.26… Read More: 4 mm2 to AWG: Closest Gauge and the 32% Overshoot »
Most converters will tell you 1.5 mm² is 16 AWG. That is arithmetically correct and practically wrong. 16 AWG is 1.31 mm² — 13% less copper than 1.5 mm². Install it against a 1.5 mm² design and you have quietly reduced what the circuit can carry. 14 AWG is the gauge to order. The gap between the two… Read More: 1.5 mm2 to AWG: Why 16 AWG Is the Wrong… »
2.5 mm² converts to 14 AWG by cross-sectional area. But 14 AWG is not what you should order. That distinction matters more going this direction than the other, and it catches people out constantly. Two answers, and you need both Gauge Cross-section Against 2.5 mm² Closest by area 14 AWG 2.08 mm² 17% less copper Safe substitute 12… Read More: 2.5 mm2 to AWG: Closest Gauge and Safe Substitute »
35 mm² converts to 2 AWG, and this is the one page on this site where the answer is simple. 2 AWG is 33.6 mm² — only 4% smaller than 35 mm². More importantly, it is one of two gauges in the entire range that actually meets the metric resistance limit for the size it pairs with. Why… Read More: 35 mm2 to AWG: The One Size That Converts Cleanly »
14 gauge wire measures 1.63 mm across, and its cross-section is 2.08 mm². Unlike most gauges, both numbers get asked about equally here. 14 AWG sits right at the boundary between people picking cable for a circuit and people picking hardware for a conductor, so this page answers both. The metric size, and the gap on either side… Read More: 14 Gauge Wire in mm and mm2: Diameter and Cable… »
16 gauge wire measures 1.29 mm across. That is 50.8 mils, or 0.0508 inches. Almost everyone asking this question wants the diameter, not the cross-section. It is a ferrule question, a terminal question, or a “will this fit the connector” question. So the diameter comes first here — but the number you need is probably not 1.29 mm.… Read More: 16 Gauge Wire in mm: Diameter and Conductor Size »
2 gauge wire measures 6.54 mm across. Its cross-section is 33.6 mm², or 66,360 circular mils. This gauge is unusual, and it is worth knowing why before you specify anything. The gauge that actually lines up Convert almost any AWG size and you land between two metric sizes with an awkward gap either side. 12 AWG converts to… Read More: 2 Gauge Wire in mm: Diameter, mm2 and Cable Size »
12 gauge wire measures 2.05 mm across. Its cross-section is 3.31 mm², or 6,530 circular mils. Both numbers get asked as “12 gauge in mm,” so both are here. The diameter is what you need for ferrules, glands and terminal ranges. The cross-section is what you need for a cable schedule — and it is not a size… Read More: 12 Gauge Wire in mm: Diameter, mm2 and What to… »
Working from a metric drawing and need the American equivalent. Converting metric to AWG has a complication the other direction does not. Metric sizes are real products, but the AWG conductor you get back is usually smaller — and a smaller conductor is not a substitution you can make quietly. 2.5 mm² is closest to 14 AWG by… Read More: mm2 to AWG: Metric Cable Sizes and Their Gauge »
Every gauge, both units, and the metric size you can actually order. A wire gauge gives you a diameter. It does not give you a cable size, and the gap between those two things is where most conversion mistakes happen. 12 AWG measures 2.05 mm across and has a cross-section of 3.31 mm². Both numbers are correct and… Read More: AWG Wire Sizes: Diameter in mm and mm2 for Every… »
