Wire gauge is a standardized measurement of the diameter of wire, often used in the electrical and manufacturing industries. The 7/64 wire size is a commonly used wire gauge measurement in these industries.

Asking about the 7/64 wire size is a vague question. It may refer to single strand diameter, bunched conductor diameter or the overall diameter of the wire, but generally it refers to the cross sectional area of the bunched/twisted conductor. The calculated cross sectional area which refers to the 7/64 wire size in mm is 14.53 mm² that is very close to the standard cable size of 16 mm² wire commonly used as a modern alternative of 7/64 wire.

However, if you are interested in other measurements and complete technical details of the 7/64 wire, we have compiled a complete list of 7/64 cable’s technical details and other helpful data.
