[′mezh·ər ‚zir·ō]
(mathematics)
A set has measure zero if it is measurable and the measure of it is zero.
A subset of Euclidean n-dimensional space which has the property that for any positive number ε there is a covering of the set by n-dimensional rectangles such that the sum of the volumes of the rectangles is less than ε.

This definition of measure zero is equivalent to definition arising from Lebesgue measure.
The set A is of measure zero in M if and only if for every coordinate coordinate system (V, h), the set ([pi] o h) (A [intersection] V) is of measure zero in [R.
