The unit for radial distance is usually determined by the context.

The vehicles must approach the target Sun-like stars at radial distances similar to the launch, about 1 au.

The field strength grows linearly with the radial distance from its longitudinal axis.

After identifying both persons as estimating their radial distance then access to the patient's file may be granted without any error.

The radial distance is also called the radius or radial coordinate.

The length of a fiber with a radial distance, e, below the neutral axis is .

However, radial distances and angles are not accurately represented.

However, the radial distance between the stars is unknown, so they are probably further apart.

The inverse relationship with the radius of curvature shows that half the radial distance requires twice the force.

The area of such a shell is where r is the radial distance from the center.
