Sure, if you count the 5 in metric seconds & the 3 in
normal units!

Allright, I've heard enough metric bashing. It's time for rebuttal...
1 kilometre = 1000 metres
1 metre = 100 centimetres
1 centimetre = 10 millimetres
1 millimetre = the tip of a ball point pen
See how easy this is...all multiples of 10. This works for weight and volume measures too.
Now you do the same comparing a mile to a yard to a foot to an inch (no calculators allowed).
