1×106

1×106 is a numeric expression that can be interpreted in more than one way depending on context. In basic arithmetic it equals 1 multiplied by 106, giving 106. In contexts where scientific notation is used but the exponent is not clearly written, the sequence can be read as 1×10^6, meaning one million.

Clarifying forms: The unambiguous representations are 106 for one hundred six; 1×10^6 or 1e6 for one million; and 1,000,000 as decimal form. The expression 1×106 without further context is therefore potentially ambiguous.

In scientific, engineering, and computing usage, the convention is to use an explicit exponent or an "e" notation to avoid confusion. For example, 1e6 equals one million, and 1×10^6 is common in formal mathematical writing. In programming languages, 1e6 is a standard numeric literal representing one million.

Notes: The term intersects with SI prefixes: 10^6 corresponds to the prefix mega-, as in megabytes (MB) or megahertz (MHz). This connection helps indicate scale when dealing with data sizes, frequencies, or other quantities on the megascale.
