Units derived from SI base units may be expressed in terms of the units listed in Chapter I.

In particular, derived SI units may be expressed by the special names and symbols given in the above table; for example, the SI unit of dynamic viscosity may be expressed as m–1 · kg · s–1 or N · s · m–2 or Pa · s.’;

(f)in Chapter II, the following row shall be deleted from the table:

‘Land registrationacre1 ac = 4 047 m2ac’

(g)in Chapter II, the final sentence shall be replaced by the following: ‘The units listed in this Chapter may be combined with each other or with those in Chapter I to form compound units.’
