Is the grit the same with emery paper and sandpaper?

No, the grit is not necessarily the same between emery paper and sandpaper. Emery paper typically uses emery as the abrasive material, which is coarser and more durable, making it suitable for metalworking. Sandpaper, on the other hand, can use a variety of abrasive materials, such as quartz or aluminum oxide, and is often used for woodworking and finishing. Therefore, while both can have similar grit ratings, their applications and materials differ.
