## How Do You Abbreviate Billion?

Billion

Noun

Billion refers to 1,000,000,000, the number one followed by nine zeros. Don’t confuse it with a million (six zeros) or a thousand (three zeros).

There are various ways of abbreviating billion:

• B
• Bn
• Bil.

B is the abbreviation that is most widely used for the sake of consistency. Notably, some people may choose to stick to
Bn, and it’s always important to select one abbreviation, so that the reader does not get mixed up. Many organizations offer a style guide so that all employees or students can use consistent terminology and abbreviations.

### When to Abbreviate

In mathematics, formal writing, within the context of records, and under many other circumstances, the abbreviation may be used.

For example:

The government released \$2B to the Ministry of Health for the current financial year. \$1B will go towards equipping hospitals with medicine, while \$1B will be used to cover surgeries.

Banks usually use abbreviations. For example, they’ll use \$1B instead of \$1,000,000,000. This method is the most convenient way to notate large amounts of money. Similarly, the abbreviation is widely used in the press. It’s more concise to use an abbreviation instead of repeating the nine zeros, especially in a headline.

For example:

The government allocated \$5,000,000,000 for the project, with a budget of \$3,000,000,000 for equipment and \$2,000,000,000 for salary.

The text lacks clarity, since large numbers distract the reader from the content.

It’s rare to find accountants recording the nine zeros in their financial analysis or profit and loss statements. Instead, you’ll see something more like this:

The government allocated \$5 bil. for the project, with a budget of \$3 bil. for equipment and \$2 bil. for salary.

Like all other abbreviations, a billion is often abbreviated in short-form communication, like memos and emails. It’s common to see large numbers abbreviated between colleagues to save space and add clarity.

When a typographical error occurs while recording the nine zeros, it alters the meaning of the text significantly. An abbreviation may help to avoid this problem.

### How to Write Billion

According to Wikipedia, the term milliard can also be used to refer to one billion, though its use in English is uncommon.

Normally, there is no space between the number and the letter B.

For example:

1B trees will be planted to protect the earth against global warming.

A billion can be used in its plural form—as billionswhere the number is uncountable or unspecified.

For example:

Billions of stars were shining.

In the next ten years, billions of dollars will probably go towards funding the education budget.

However, where the word billion is preceded immediately by a number, the plural form billions should not be used. For example, this road costs \$10 billion to build.

### Energy Industry

Natural gas production and trade is measured in billion cubic meters of natural gas. In this industry, billion cubic meters is abbreviated as bcm. This measurement may be applied to represent energy content.

## What Does Billion Mean?

Wikipedia defines a billion as either one thousand million (1,000,000,000) in American English, or one million million (1,000,000,000,000) in British English. The United Kingdom officially switched to the American/French definition in 1974, but you’ll still come across the secondary definition on occasion.

In scientific notation, a billion is written as 1 × 10^9. The metric prefix giga means 1,000,000,000 times the base unit, and its symbol is G.
