Size zero Size zero Size zero or size 0 is a women's clothing size in the US catalog sizes system. Size 0 and 00 were invented due to the changing of clothing sizes over time (referred to as vanity sizing or size inflation), which has caused the adoption of lower numbers. For example, a 2011 size 0 is equivalent to a 2001 size 2, and is larger than a 1970 size 6 or 1958 size 8. Modern size 0 clothing, depending on brand and style, fits measurements of chest-stomach-hips from 30-22-32 inches (76-56-81 cm) to 36-28-36 inches (90-71½-90 cm). Size 00 can
Size consistency and size extensivity size consistent, then the energy of the supersystem A+B, separated by a sufficiently large distance so there is essentially no shared electron density, is equal to the sum of the energy of A plus the energy of B taken by themselves (formula_1). This property of size consistency is of particular importance to obtain correctly behaving dissociation curves. Others have more recently argued that the entire potential energy surface should be well-defined. Size consistency and size extensivity are sometimes used interchangeably in the literature, However, there are very important distinctions to be made between them.
