This is literally something I thought up in 20 minutes. That's how easy it is to get you mind around
octal. By the way, octal is base-eight
counting (for more on how number bases work, see my essay, Counting Systems
Compared). I am not going to
develop this any more – at least not in the near future. But I thought some of you might like to see
the raw data – it's fairly straightforward.
Remember, in octal, eight looks like 10.

Octal Time:
The below
text is written in decimal.
Octal (a)
time: 16 hr. Day (clock face numbered 1-8 with 8 sets of 8 min./sec. each)
second
conversion: 86 400/24 = 65 536/16
1 sec =
1.318359375 sec
1 min = 84.375
sec
1 hr. = 5 400
sec
1 day = 8 6400
sec.
Octal (b)
time: 30 hr. day (clock face numbered 1-15 with 15 sets of 4 min./sec. each)
second
conversion: 86 400/24 = 108 000/30
1 sec = 0.8 sec
1 min = 48 sec
1 hr. = 2 880sec
1 day = 8 6400
sec.

Octal Measurement:
I'm not sure how
long these units should be, but I am thinking of 1 inch = 1 international inch
(or 2.54 cm)
|
1/8 inch |
1 inch (1/8
foot) |
1 foot |
1 yard (4 feet) |
1 fathom (8
feet) |
(the fathom is
the next ‘metric’ unit after the foot; yard bears the same relationship to a
fathom as a cubit does to one of our yards.)
