One million is a number equal to 106 = 1003 = 1,0002 = 1,000,000 = 1E6 = one followed by six zeroes (in both the short scale and the long scale).[1][2] It is both a square number and cubic number. It is often used as hyperbole or exaggeration to represent an indefinitely large number. A million is one of the first names of numbers to be generally considered big by most people's standards. The name came from the Old Italian word "millione", which serves as an augmentative of "mille", meaning thousand, derived from Latin.[3]

## Examples

• One million milliseconds is approximately 16.67 minutes, one million seconds is approximately 11.57 days, one million minutes is about 1.9 years, one million hours is about 114 years, one million days is about 2,739 years, one million weeks is about 19,178 years, one million months is approximately 83,333 years, one million years is 12 million months, one million decades is 10 million years, one million centuries is 100 million years, and one million millenniums is one billion years. One millennium has 8.76 million hours.
• One million cubic centimeters (cm3) equals one cubic meter (m3). Therefore, one million grams (which is equivalent to 1000 kilograms) of water approximately equals one cubic meter (m3).
• Sbiis Saibian computed that if a person walked one thousand miles every 31 days, after 75 years, that person would have managed to walk about 8.83 million miles.[14]
• A tower of a million people is about four times higher than the International Space Station.
• A million one-dollar bills would cover the area of two football fields.
• The country of Kazakhstan is slightly larger than a million square miles in area; and the country of Egypt is slightly larger than a million square kilometers in area.[15]
• The state of Alaska is about 1.7 million square kilometers in area.[16]

## In googology

• In Greek-based number-naming systems, a million is associated with SI prefix mega-, and with SI prefix micro- in Latin systems.
• A million is the boundary between class 1 and class 2 numbers in Robert Munafo's idea (see class for more).[17]
• A million appears in the definition of Aarex's Graham Generator as well as googolisms formed using it such as forcal.
