Ramanujan's formula for pi gives the accurate value of pi up to 6 decimal places, but this is only the first term in an infinite series. This number alone is sufficient to calculate the circumference of the Earth with a maximum error of just 1 meter. It is to be noted that while Ramanujan's formula takes one term to calculate up to six decimal places, it takes Leibniz about 5 million terms. Ramanujan's formula could do it in one term, and each successive term adds another eight decimal places to the value of pi. This formula holds absolutely true for finding the value of pi, but there is no clear understanding of how he came up with the numbers in his formula, like 9801 and 1103.
