1 billion = 1000 million

To give you some monetary context, if you were to earn $100,000 per year it would take you 10 years to earn $1 million. To reach $1 billion would require you to save every penny you earnfor 10,000 years.

Well, like so many things when it comes to measuring up, it can vary a bit depending on where you are. In the US, a billion has always been < Dr. Evil > ONE THOUSAND MILLION < / Dr. Evil > . In numbers, that's 1,000,000,000 with, count 'em, nine zeroes.

Million to Billion Converter (1)

In the UK, traditionally a billion was < Dr. Evil second attempt > ONE MILLION MILLION < / second attempt > . That's 12 zeroes (1,000,000,000,000). But what's a difference of three zeroes between friends? A lot, as it happens.

A doctor telling you that you have a billion seconds to live would receive a stony reception in the US, as that adds up to 32 years. In the land of red phone boxes, cups of tea and roast beef, though, it would mean 32,000 years. Suddenly, British immortality is explained: Doctor Who regenerating across centuries,and Mick Jagger, looking youthful at just 240 years old - it all makes sense.


In 1974, the UK government decided to try on a leather jacket and talk like the Fonz, and it began using the US sense of "billion" for all official figures released - that's a thousand million. Nine zeroes. It's basically a universal now.1

What does a billion look like?

Some things are too extraordinary to visualise. Can you even imagine a billion dollars? A billion cats? A billion jars of Nutella, all with your name on them?

Let's go back to the idea that a billion seconds is 32 years. How many years, then, is a million seconds? Have a little think. The answer? None. It is no years. It is less than 12 days. That's how vast the difference is between million and billion.

Now raid your piggy bank and see if you can find a billion pennies or cents to pile up. That's 10 million dollars, pounds or euros, so it's probably not worth wasting your time actually smashing open Percy Pig right now. But just imagine: one billion cents in a stack would be 870 miles high.Or if you laid them side by side in a line, it would stretch 6,213 miles, which would reach 2/3 of the way round the circumference of Mercury.

We hope you've found this article and converter helpful. When you next hear someone talk about money in the billions, you'll know how much that equates to.

If you think the billion is a huge number, though, it's nothing compared to the size of the trillion.
