Page "Centimetre–gram–second system of units" Paragraph 7

The units gram and centimetre remain useful as prefixed units within the SI system, especially for instructional physics and chemistry experiments, where they match the small scale of table-top setups.

However, where derived units are needed, the SI ones are generally used and taught instead of the CGS ones today.

For example, a physics lab course might ask students to record lengths in centimetres, and masses in grams, but force ( a derived unit ) in newtons, a usage consistent with the SI system.
