# Number and Word to Standard Notation Calculator

## Calculator Use

Convert number and word combinations into numbers only. This calculator converts a number word phrase such as 2.75 million into its numerical equivalent. The number word phrase 2.75 million converts to numbers in standard notation as 2,750,000 and also scientific notation as 2.75 x 10^{6}.

## What is Standard Notation?

Standard notation of a number is when a number is written with only number digits. This is the typical way to write numbers since words are not used in standard number notation. You may see standard notation numbers with thousand separators (commas) and decimal indicators (periods), but not with words like "trillions" or "hundredths."

## Why Use Number Word Notation?

Number and word notation is usually used when exact figures are not required but the magnitiude of a value is important in explaining a point or story.

### Example number word notation: The U.S. national debt is more than 16.76 trillion dollars.

Converting from number word form to standard number notation:

16.76 trillion = 16.76 x 10^{12} = 16,760,000,000,000

If you need to say the number 16,760,000,000,000 you would say, "sixteen trillion, seven hundred sixty billion."

### Example number word notation: The fastest CPU operation executes in less than 4 millionths of a second.

Converting from number word form to standard number notation:

4 millionths = 4 x 10^{-6} = 0.000004

If you need to say the number 0.000004 you would simply say "four millionths."

### Example number word notation: What is 2 millionths of a billionth of a second?

Converting from number word form:

2 millionths = 2 x 10^{-6}

1 billionth = 1 x 10^{-9}

2 Millionths of 1 Billionth

= 2 x 10^{-6} * 1 x 10^{-9}

= (2 * 1) x 10^{(-6 + -9)} = 2 x 10^{-15} seconds.

## What is Standard Form?

"Standard form" is typically used in England and Great Britain to refer to the scientific number notation that the US calls "scientific notation." Standard form and scientific notation are essentially the same way to refer to the notation used to represent very large or very small numbers such as 4.959 × 10^{12} or 1.66 × 10^{-24}.
