Has anybody got the calculation for interprating overrevs?

If your DME says you have (say) 1,000 Type 1 overrevs, how many second or crankchaft revolutions is that?

I know I nearly fainted when I saw my engine had 22,000 Type 1 overrevs, but that was about 100 hours run time ago and I'd already had the car for a year when I discovered it...... Looks like the car had been on the dyno in its previous life, but up to now no mechanical problems, touch wood.
