K

The letter "K" is often used in finance to represent the number 1,000. For example, a price of $1,000 might be written as $1K. This convention is common in both the United States and the United Kingdom.

In some cases, the letter "M" is used to represent the number 1,000,000. For example, a price of $10,000,000 might be written as $10M. This convention is less common than the one described above, but it is still used occasionally.

It is important to note that the letters "K" and "M" are not official abbreviations for the numbers 1,000 or 1,000,000. However, it is a widely accepted convention that is used by many people in the financial world.

If you are ever unsure whether a particular use of the letter "K" or "M" is referring to the number 1,000 or 1,000,000, it is always best to ask for clarification.
