ABC - DEF - GHI - JKL - MNO - PQRS - TUV - WXYZ Unit prefixes of the International System of Units (SI)
In order to keep figures short and presentable, SI prefixes are often attached to units such as m (meter) or g (gram).
For example, a substance weighing 0.000 000 001 g may be described more simply as 1 ng (nanogram) or as 1000 pg (picograms).
Common prefixes of the International System of Units (SI) are:
