Manheim-Hudec scale

The Manheim-Hudec scale is a scale measuring the intensity changes in the space-time continuum cause. The scale reads from 0 to 10, with 10 resulting in the destruction of the known universe. The scale was created by Drs. and Hudec.

In 2373, when the Borg invaded the Federation, the USS Enterprise (NCC-1701-E) encountered a disturbance of a magnitude of 7.83 on the Manheim-Hudec scale, which saw the Borg in control of Earth and the majority of the Alpha Quadrant. 

In the same year, as a result of the same event, the USS Cantabrian (NCC-24705) shuttlecraft away team, led by Noel Turner, encountered the same disturbance that threw them into the mid-2270s. This event had a disturbance of the magnitude of 6.2208 on the scale.
