Here's a more detailed explanation:

• Roman Numerals: In the Roman numeral system, "M" represents 1,000. 
• "K" as "Kilo": The letter "k" (or "K") is an abbreviation for "kilo," which is a prefix meaning "thousand" in the metric system and SI units (e.g., kilogram, kilometer). 
• Context is Key: The context determines whether "K" represents a Roman numeral or "kilo." For example, "1000" in Roman numerals is "M", while "1000 meters" can be written as "1 km" or "1k meters". 
• Example: $10K can mean $10,000 
• Greek Root: The prefix "kilo" comes from the Greek word "chilioi" meaning "a thousand"
