Iwao's calculation took 121 days to finish and needed 25 virtual machines.

The previous world record, calculated in November 2016 by Peter Trueb, calculated Pi to around 9-trillion decimal places fewer than the number calculated this year by Google.

Today is 14 March, also known as Pi Day (due to being written as 3/14 in the United States).

Iwao's feat is the first pi record calculated on the cloud.

Running the calculation on the cloud gives the mathematically curious a major upgrade in convenience, Google said.

How has Google used Pi Day to break a Guinness World Record?

Even with Google's infrastructure on her side, determining trillions of digits was no simple task. She told CNN that it was her childhood dream to create such a record. Pi is used in engineering, physics, supercomputing and space exploration - because its value can be used in calculations for waves, circles and cylinders.

Iwao said in the announcement that's she's been fascinated with pi since she was 12- and never imagined breaking the Guinness World Record. It's almost nine trillion digits more than the previous world record set by Peter Trueb in November 2016.

This is the first time the pi record has been broken using a commercial cloud service, Google Cloud Platform, rather than supercomputers and custom-built PCs, noted Yee in his own blog post.

In mathematics pi is the ratio of a circle's radius to its circumference, has far more digits that continue infinitely without repetition.

The pizza: For a lot of people, Pi Day is all about the related sales on pizza, and Thrillist has a list of the deals at chains and restaurants around the US. When I was a kid, I downloaded a program to calculate pi on my computer, ' Emma said. "At the time, the world record holders were Yasumasa Kanada and Daisuke Takahashi, who are Japanese, so it was really relatable for me growing up in Japan".
