GB/T 18776-2002
ActiveTolerance dimensions--Conversion form inches into millimetres and vice versa
公差尺寸 英寸和毫米的互换算
Application Summary AI generated
This standard specifies the conversion rules between inch and millimeter units for tolerance dimensions, ensuring consistent interpretation of dimensional specifications across different measurement systems. It is applied in engineering design, manufacturing, and quality inspection contexts where products or components are specified in both imperial and metric units, such as in international trade, machinery production, and aerospace industries. The standard is critical for avoiding conversion errors in tolerance-sensitive applications like precision machining and assembly.
