In figures, 1 million is written as 1 followed by six zeros, or 1,000,000. This number is easily understood as one thousand times one thousand. The word "million" is from the Italian "millione," which means "thousand."
Another way of expressing 1 million is using the Roman numeral system, wherein 1 million is written as a capital letter M with a bar on top. The letter M has a value of 1,000, and placing a bar on top of it multiplies the value with another 1,000.
One million can be better visualized using paper money. A dollar bill weighs 1 gram, so 1 million one-dollar bills weigh 1 ton. Using the unit of time, 1 million seconds is equal to 11.57 days.
