Which measuring tool provides a rough approximation of grade?

The general purpose level is effective for providing a rough approximation of grade due to its straightforward design and function. This tool typically consists of a horizontal vials that allow the user to quickly discern whether a surface is level or not. When estimating the grade or slope of a surface, one can set the level along the length of the area, checking for any deviation from the level position.

In situations where a rough estimation is adequate, such as initial layouts for plumbing installations where precision may not yet be critical, the general purpose level serves as a handy tool. Its simplicity and ease of use make it suitable for basic grading tasks, allowing a quick assessment of whether a surface is on the right slope.

While tools like the transit level, laser level, and plumb bob have specific applications for more precise measurements, they are generally more suited for accurate leveling and alignment tasks rather than a quick estimation of grade.
