The national average for a new shower installation project, when performed by a capable contractor, is $2,689. At the low-end of the normal cost range, homeowners are paying $1,109, and at the high end of the average range theyâre spending $2,459.
While mile is a unit of distance on land, a nautical mile is used to measure distances at sea. 1 nautical mile = 1.151 mi. 1  Kilometer vs Mile.  Celsius vs Fahrenheit.
(By the way, the nautical mile is about 1.15 larger than the statute mile used by land lubbers.) Since [speed] = [distance] divided by [time], if we measure a small distance (or length) in a small time we can do the math and figure our speed.
