When we become aware of the the next round of actions by the CIPM, and the next round of resolutions by the CGPM, we will know which, if any, changes to SI are officially declared. Until then, the text that you quoted from Draft 5 of a *proposed* revision of SI 10 is placing the cart before the horse. > Litre is a special name for cubic decimetre. This statement is a *variation* of Resolution 6, Declaration 2., of the 12th CGPM (1964), reported on page 131 of the BIPM Booklet (1998). Why did you alter the wording (deleting: several words and phrases)? By either wording, we have no dispute on the meaning of declaration 2. > Is or is not cubic decimetre an SI unit? By the BIPM Booklet (1998), the cubic meter is the one, and only one, "SI unit" of volume. The cubic millimeter, the cubic centimeter, the cubic decimeter, the cubic dekameter, etc. are submultiples or multiples respectively of the only "SI unit" of volume, the cubic meter. The proposed wording that you quoted (Draft 5) for SI 10 would have us believe that the milliliter is an SI unit since it carries a prefix, but the liter is not an SI unit, since the word itself carries no prefix. The BIPM Booklet is clear. The liter is a *Non-SI unit accepted for use with the International System*. The liter is listed on page 105, Table 6, among other Non-SI units accepted for use with the SI. Although not explicitly stated for each of the decimal submultiples and multiples of the liter, by implication, these are also *not* SI units but are nevertheless accepted for use with the International System.
