French Revolution Clock?

Question

I was wondering, on the french revolution clock there are 10 hours, every hour has 2.4 normal hours, could someone please tell me the exact minute of which each hour on a normal clock goes by on an hour of the french revolution clock?

Answer 1

Decimal time is the representation of the time of day using units which are decimally related. This term is often used to refer specifically to French Revolutionary Time, which divides the day into 10 decimal hours, each decimal hour into 100 decimal minutes and each decimal minute into 100 decimal seconds, as opposed to the more familiar standard time, which divides the day into 24 hours, each hour into 60 minutes and each minute into 60 seconds.

There are exactly 86,400 standard seconds (see SI for the current definition of the standard second) in a standard day, but in the French decimal time system there are 100,000 decimal seconds in the day, so the decimal second is shorter than its counterpart.

Decimal to Standard

One decimal second is 86,400/100,000 = 0.864 standard seconds.

One decimal minute is 1,440/1,000 = 1.44 standard minutes, or 1 standard minute and 26.4 standard seconds.

One decimal hour is 24/10 = 2.4 standard hours, or 2 standard hours and 24 standard minutes.

One hundredth of a day is 14 standard minutes 24 standard seconds, or approximately 15 minutes.

Standard to Decimal

One standard second = 1.15740 decimal seconds

One standard minute = 69.44 decimal seconds (or .69 decimal minutes)

One standard hour = 4,166.67 decimal seconds (or 41 decimal minutes and 67 decimal seconds)
