This is coolbert:
More calculation within the context of the Battle of Jutland, 1916. The dollar value [2019 dollars American $] of those twenty-eight British battleships present at Jutland was?
The Grand Fleet [British] consisting of one-hundred fifty-one warships, twenty-eight of which classed as battleships.
Strictly with regard to British battleships at Jutland the cost of those massed vessels alone approximates to $SEVEN BILLION dollars American in current  value.
1. British Grand Fleet at Jutland consisted of twenty-eight battleships.
2. Approximate cost [rough estimate] of each British battleship  about two million English £ pounds.
3. One £ pound value in 1916 worth five American $ Dollars.
4. From an inflationary calculator an item costing one American $ dollar  that same item would cost approximately twenty-five times in an American $ dollar .
5. Calculation: Twenty-eight X two million X five X 25 approximately = $Seven billion American Dollars .
A tidy sum whatever way you count and calculate, assumptions all approximate, again, strictly that amount for British battleships only.
Anybody have a problem with my methodology or calculations?
