In solving problems related to linear/angular conversion, must the units for angular displacement be in revolutions?

In the context of linear to angular conversions in biomechanics, it is not necessary for angular displacement to be expressed in revolutions. Angular displacement can be measured in various units, including degrees, radians, or revolutions, depending on the context of the problem or the equations used.

Revolutions are one way to express angular displacement, but they are not the only option. For instance, radians are often preferred in physics and engineering because they relate directly to the properties of circles (such as arc length), making calculations more straightforward and integrative with other measurements.

Using different units is acceptable as long as you ensure consistency throughout the problem. When performing conversions, what matters most is that the units are appropriately converted and understood within the context of the equations being applied. Therefore, it is entirely possible to work with angular displacement in units other than revolutions without encountering any issues in your calculations.
