使用的尺子怎么说英语

In English, the word for a ruler is "ruler." It is a flat, straight tool that is used for measuring lengths and distances. It is typically made of wood, plastic, or metal and has markings on it that show the unit of measurement, such as inches or centimeters. To use a ruler, you place it alongside the object you want to measure and read the measurement at the point where the object ends. You can also use a ruler to draw straight lines or to align things.
