Claim: The term million uses the same prefix and symbol in both the short and long scale systems.
Evidence: The meaning of the word "million" is common to the short scale and long scale numbering systems, unlike the larger numbers, which have different names in the two systems. Physical quantities can also be expressed using the SI prefix mega (M), when dealing with SI units; for example, 1 megawatt (1 MW) equals 1,000,000 watts. It is commonly abbreviated as m (not to be confused with the metric prefix for 1×10) or M and MM ("thousand thousands", from Latin "Mille"; not to be confused with the Roman numeral MM = 2,000), mm, or mn in financial contexts.
