3 hours = 3 hours PAST 12 o'clock = (3 x 1 billion) - 4.6 billion = 3 billion - 4.6 billion = -1.6 billion years = 1.6 billion years ago
6 hours = 6 hours PAST 12 o'clock = -1.6 billion years + (3 x 1 billion) = -1.6 billion + 3 billion = 1.4 billion years ago
If the time now is T hours (on a 24 hour clock), then the answer is mod(21 - T, 24) hours.
7 pm. In this respect, clocks start from midnight.
That sounds like a reading of the 24 hour clock: For example 1800 = 18 hundred hours = 6pm in 12 hour clock. In the 24 hour clock, the time is the number of hours and minutes since the start of the day. When the time is an exact hour, it is usually read n hundred hours. Thus 24 hundred hours is 24 hours since the start of the day. As there are 24 hours in a day, it represents the midnight at the end of a day, as oppose to 00:00 which represents the midnight at the start of the day. The midnight at the end of one day is the same as the midnight at the start of the next day. For example 24:00 Tuesday is the same time as 00:00 Wednesday. Normally, 00:00 would be used for midnight, but occasionally, 24:00 may be used to emphasise the end of a day; the last normal time (hour and minute) of a day would be 23:59.
its a whole 24 hours dumb dumb
4pm to midnight is 8 hours.
34
Yes we do. We usually measure AM from midnight to 12 noon, and PM from noon to midnight. However - travel-orientated situations use the 24-hour clock to avoid confusion.
If the time now is T hours (on a 24 hour clock), then the answer is mod(21 - T, 24) hours.
3pm (civilian time) is 1500 in military or EU time. It is based on the 24-hour clock that begins at midnight,with 1500 beingg 15 hours past midnight.
On the 24hr clock this means 5 minutes to midnight or 11:55pm.
Add 12 to the number representing hours, from 1:00 pm to just before midnight.
2000 Hours ('hours' is the Army or Air Force designation, US Marines call it 2000) would be 8pm civilian time. The 24-hour clock used by the military and in Europe starts at midnight, so 2000 is 20 hours past midnight.
On the twenty-four hour clock, 00.05 is five minutes after midnight.
1.2 hours = 12/10 = 1 hour 12 minutes
Giga means billion. 5 gigas equals 5 billion.
1 000 000 000 hours (I dont know what maqny hours are).
A normal clock has twelve hours and it goes through two cycles of that period every day. There are occasions when you need to know whether it the time referred to is in the fist cycle (midnight to noon = am) or the second (noon to midnight = pm).
