≈ GBP (£):
based on the info that £1 000 000 == 50 000 056 credits (source: "voyage of the damned"; TARDIS wiki: "The Tenth Doctor said that £1,000,000 was equal to 50,000,056 credits"), your number is divided by 50.000056 (the value of £1). however, if we assume that inflation does exist, this may only be accurate on christmas day, 2008. (rounds to the nearest 2 decimal places because that seems right for currency)
