How many litres are there in a billion gallons?

1 Imperial gallon (UK gallon) = 4.54609L

1 US gallon = 3.785412L

1 billion in UK (and Europe) = 10^12 or 10^9 (both scales still in use in UK)

1 billion in USA = 10^9

Therefore

1 billion gallons in UK = 4,546,090,000,000L or 4,546,090,000L depending on whether you choose to use the long scale or the short scale

1 billion gallons in USA = 3,785,412,000L

I don't know about the American gallon but there are 4.51 billion litres to 1 billion English gallons.

$2.87 per gallon for regular unleaded. I have really cut out a lot of extras like eating out as often and getting salon manicures and pedicures because of the rising prices.

3.785411784 billion Litres for Gallons (US)

4.54609 billion litres for Gallons (UK)

1 000 000 000 gallon [US, liquid] = 3 785 411 800 liter

1 000 000 000 gallon [UK] = 4 546 089 999.999 999 liter

The answer is correct.....just remove the decimal:

4, 546,089, 999 or rounded: 4, 546, 090, 000

Here's a great online resource for that
