Was watching a British documentary and tripped over an expression brand- new to me: the number 1,400,000 was expressed by the Brit. narrator as "fourteen hundred, thousand". Really caught me by surprise as I have never heard that before and would never express a number that way; I would say 1.4 million or one- million, four hundred thousand, as would all Americans at least to the best of my knowledge.
Again, the words are the same and make perfect sense, it is just the presentation that is different.

"one-million four hundred thousand" = 5 words = 8 syllables = 33 letters including spaces
"fourteen hundred thousand" = 3 words = 6 syllables = 25 letters including spaces
"1.4 million" = 2 words = 5 syllables = 11 alphanumeric characters including spaces
"1,400,000" = 1 "word" = ? syllables = 9 alphanumeric characters including spaces
If the situation allows for solely numbers, "1,400,000" requires the fewest words and alphanumeric characters, so it saves time, ink, electricity and probably other resources, so I vote that it should be the default. I would pronounce it economically as "one point four million". Nice ... and concise
If the number must consist of all letters/words, then "fourteen hundred thousand" is more economical than "one-million four hundred thousand" for the same reasons.
