'Standard' in the Bible

Now there was a wall surrounding the outside of the temple. The measuring rod in the man’s hand was six units of 21 inches; each unit was the standard length plus three inches. He measured the thickness of the wall structure; it was about 10 feet, and its height was the same.

“These are the measurements of the altar in units of length (each unit being the standard length plus three inches): the gutter is 21 inches deep and 21 inches wide, with a rim of nine inches around its edge. This is the base of the altar.

The dry measure and the liquid measure will be uniform, with the liquid measure containing 5½ gallons and the dry measure holding half a bushel. Their measurement will be a tenth of the standard larger capacity measure.

The quota of oil in liquid measures will be one percent of every cor. The cor equals 10 liquid measures or one standard larger capacity measure, since 10 liquid measures equal one standard larger capacity measure.
