A svedberg unit (symbol S, sometimes Sv) is a non-metric unit for sedimentation rate. The sedimentation rate for a particle of a given size and shape measures how fast the particle 'settles', the sedimentation. It is often used to reflect the rate at which a molecule travels to the bottom of a test tube under the centrifugal force of a centrifuge.[1] The svedberg is actually a measure of time; it is defined as exactly 10−13 seconds
