Pi digits
Here you get the pi digits you need – the first 100, 1,000 or up to 10,000 decimal places – and can look up a single position or find where a number sequence first appears.
Example: What do you want: Show digits · Number of decimal places (1–10,000) 100 → Result: π to 100 decimal places. Source: OEIS A000796, Decimal expansion of Pi, with the b-file of 20,000 digits; the first 10,000 decimal places computed here match it digit for digit (read 14.10.2026). Updated: .
How it is calculated
π = 3.14159 26535 89793 23846 26433 83279 50288 41971 69399 37510 … These are the first 50 decimal places. The tool shows up to 10,000 of them, finds the digit at any position and searches number sequences.

Counted from the decimal point, the 10th decimal place is 5, the 100th is 9 and the 1000th is also 9. At decimal place 762 six nines in a row begin – the so-called Feynman point. The year 2000 first shows up at place 600.

Each digit appears close to 1,000 times, as expected if the digits are evenly spread – a property that is observed but not proven for π. For everyday use a few digits are enough: the circle calculator works with full precision, and the significant figures calculator rounds results sensibly.
How the digits are calculated
The tool computes the digits on your device with Machin’s formula π = 16·arctan(1/5) − 4·arctan(1/239) and exact integer arithmetic plus 12 guard digits. A search covers the first 10,000 decimal places only; longer sequences such as a full date (8 digits) usually appear much later in π.
Frequently asked questions
What are the first 10 digits of pi?
3.1415926535 – that is 3 followed by the decimal places 1415926535.
What is the 100th digit of pi?
The 100th decimal place of π is 9.
Where are the six 9s in pi?
Six nines in a row start at decimal place 762; this spot is known as the Feynman point.
Can I find my birthday in pi?
Yes, enter it as a digit sequence. About two thirds of all four-digit sequences appear in the first 10,000 places – 0704 starts at place 9881 – while longer dates usually do not.
Does pi ever end or repeat?
No. π is irrational, so its decimal expansion neither ends nor repeats.
