But, what was the total sea area under British control?

Answer 1

The British Empire and Commonwealth
The greatest extent of the British Empire was achieved between 1918 and 1922. The figures exclude the eastern seaboard of the United States, which became independent long before the British colonial expansion of the 19th century.

14,157,000 sq. miles (36,666,630 sq. km.):-)

Answer 2

Have you not heard "Brittania rules the waves" as an island they had no choice but to explore. In exploring Britain became in those days a naval "SUPER POWER", hence they colonised
many areas of the world, places bigger than their own country e.g. Australia. The combined mass of land they conquered and colonised at the height of their power far out sizes any other country today. Guess why we have the Commonwealth countries
They were at first the "BRITISH COMMONWEALTH". Why do so many countries have English as a Language

Answer 3

the definition of sea control is not clear nowadays, imagine at the times of the british empire.
concepts such as territorial waters, international waters etc have been defined after ww2 and are still a matter of discussion so you wont get a satisfactory answer to your question

Answer 4

You are not going to get definitive answers. It could only be an impossibly vague estimate that would hold up to no measure.
