The term "1:64" refers to a scale ratio commonly used in modeling and toy manufacturing. In this context, it means that one unit of measurement on the model represents 64 units of the same measurement in real life. For example, a die-cast car made at a 1:64 scale would be 1 inch long if the actual car is 64 inches long. This scale is particularly popular for hot wheels and other miniature vehicles, allowing collectors and enthusiasts to create detailed displays. The 1:64 scale provides a balance between size and detail, making it manageable for storage while still showcasing intricate designs.
