What is 30 billion in figures?

30 billion

= 30 thousand million

= 30,000,000,000

= 3 x 1010

"Billion" is widely taken to mean "one thousand million" (as in the calculation above). However, the traditional British sense is "one million million". If there is any ambiguity, it is always wise to check which sense applies in a particular context.

Using the British sense, the answer to this question would be:

30,000,000,000,000

= 3 x 1013
