Rationale

Revision to correct the parenthetical SI unit conversions from Annex A2- Permitted Variations in Dimensions—Inch-Pound Units. The purpose of this revision is to correct the SI values to maintain consistency in the conversions. Currently the conversions, although for information only, are not consistent with respect to significant figures. When specifying to A480M, the SI unit values in Annex A3 must be used, and these values are not part of this WK.
