The calculation was completed with 25 virtual machines in 121 days and took up 170TB of data.
Iwao, a computer scientist and software engineer whose official title is cloud developer advocate, used y-cruncher, a program created by US software developer Alexander J. Yee that has been used in many previous pi record breakings. Using the program y-cruncher on a Google Compute Engine cluster, she ate through 170 terabytes of data over about four months.
She works as a Cloud Developer Advocate at Google's office in Osaka, Japan. "There is no end with pi, I would love to try with more digits", she said.
Iwao told the BBC that she's not done with pi. This is the first time the Pi calculation world record was ever broken in the cloud, and it breaks the most recent world record breakage, that of Peter Trueb in November of 2016. It is significantly used in geometrical calculations. Google and Yee broke Trueb's record by almost 9 trillion digits.
Ms Iwao said she had been fascinated by the number since she had been a child.
Even with Google's infrastructure on her side, determining trillions of digits was no simple task.
In mathematics pi is the ratio of a circle's radius to its circumference, has far more digits that continue infinitely without repetition.

'I'm really happy to be one of the few women in computer science holding the record, and I hope I can show more people who want to work in the industry what's possible'.
