We still use Roman numerals for some accounting methods, while large figures are designated by the Greek alphabetic equivalent of the specific term. As a young banker in the mid-80s, I learned what had been taught for many decades before, that we abbreviate thousands in our analysis with a letter M. M is the Roman numeral for thousand and MM is meant mm meaning to convey one thousand-thousand — or million. To take it further; one billion would be shown as $1MMM or one-thousand million. “M” is one of the simplest abbreviations for million, making it a convenient choice for use in everyday communication, especially online, where space and time are in demand. Including a million in an Instagram caption or Twitter post that can only contain a limited number of words saves space.
What does it mean to have a million dollars?

To take it further; one billion would be shown as $1MMM or one thousand million.

We are more likely to see a headline that reads the government spent $60B on a new project.
