Convert the following time to 12 hour clock.
1) 0010 hours
2) 1800 hours

Answer 1

• 1925, 0910
• 12:10 a.m., 6:00 p.m.

Explanation:

24-hour time has 12 hours added for p.m. The time is written as HHMM, a 4-digit number of "hours." (The two right-most digits are minutes.)

1) 7:25 p.m. ⇒ 1925 hours

2) 9:10 a.m. ⇒ 0910 hours

__

12-hour time starts at midnight, 12:00 a.m. That corresponds to 0000 hours in 24-hour time. Anything beyond 1200 hours is afternoon, p.m.

1) 0010 hours ⇒ 12:10 a.m.

2) 1800 hours ⇒ 6:00 p.m.
