A novel apparatus and method for use in measuring surface slope is disclosed. In a preferred embodiment, the measurement apparatus includes a fluid case having an arch of flat segments forming a sloped ceiling. In another preferred embodiment, a smooth curve, instead of a series of flat segments, is formed by reducing the length, and increasing the number, of the constant slope flat segments. A method for measuring the slope of a surface includes providing a measurement apparatus, placing the measurement apparatus adjacent the surface and reading an indicator corresponding to the slope of the surface.
