To remember the value to six decimal places, the mnemonic "How I Wish I Could Calculate Pi" can be used - the number of letters in each word in the sentence gives 3.141592.
One way to remember the first few digits of pi is to count the letters in the words of this phrase: “How I need a drink, alcoholic of course, after the heavy lectures involving quantum mechanics.”

To memorize the first 1,000 digits, you simply place images into your memory palace and go through the journey over and over again until you think you can recall each image in the correct order from memory.
approximately 3.14In decimal form, the value of pi is approximately 3.14. But pi is an irrational number, meaning that its decimal form neither ends (like 1/4 = 0.25) nor becomes repetitive (like 1/6 = 0.166666...). (To only 18 decimal places, pi is 3.141592653589793238.)
The first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.
According to the list, the person who holds the record for reciting the most digits of pi from memory is an individual from India, who recounted 70,030 digits in 17 hours on Oct. 21, 2015. In Canada, the record was achieved by Chun Wang in 2017, who recalled 8,148 digits of pi in three hours and 40 minutes.
Lu Chao of ChinaThe current Guinness World Record is held by Lu Chao of China, who, in 2005, recited 67,890 digits of pi.

A mnemonic used by physics students to remember the Maxwell relations in thermodynamics is "Good Physicists Have Studied Under Very Fine Teachers", which helps them remember the order of the variables in the square, in clockwise direction.

It is also possible to use the rhythm and sound of the spoken digits themselves as a memorization device. The mathematician John Horton Conway composed the following arrangement for the first 100 digits,
The most common mnemonic technique is to memorize a so-called "piem" (a wordplay on "pi" and "poem") in which the number of letters in each word is equal to the corresponding digit of π. This famous example for 15 digits has several variations, including:
Another mnemonic system used commonly in the memorization of pi is the Mnemonic major system, where single numbers are translated into basic sounds. A combination of these sounds creates a word, which can then be translated back into numbers.
It is possible to construct piphilogical poems in Chinese by using homophones or near-homophones of the numbers zero through nine, as in the following well known example which covers 22 decimal places of π. In this example the character meaning "mountain" (山 shān) is used to represent the number "three" (三 sān ), the character meaning "I" (吾 wú) is used to represent the number "five" (五 wǔ ), and the characters meaning "temple" (寺 sì) and "die" (死 sǐ) are used to represent the number "four" (四 sì ). Some of the mnemonic characters used in this poem, for example "kill" (殺 shā) for "three" (三 sān ), "jug" (壺 hú) for "five" (五 wǔ ), "happiness" (樂 lè) for "six" (六 liù) and "eat" (吃 chī) for "seven" (七 qī ), are not very close phonetically in Mandarin/Putonghua .
