120 minutes in hour
120 minutes is 2 hours, because one hour holds 60 minutes. Write it as 2:00 or as two hours; it is not 120 hours.
how many minutes in 24 hour
A 24-hour day holds 1,440 minutes, because 24 × 60 = 1,440. That is the answer to how many minutes in 24 hour, how many minutes are in 24 hours, and 24 hours how many minutes. The extra hyphen in 24-hours does not change the product.
A 12-hour clock face shows 12 hours, which is 720 minutes, then repeats with a.m. and p.m. A 24-hour clock writes 00:00 through 23:59 and still contains the same 1,440 minutes in a civil day. The format changes. The minute count does not.
120 minutes to hour is the short conversion: divide by 60. 120 ÷ 60 = 2. 90 minutes in hour is 90 ÷ 60 = 1.5 hours, which you can also write as 1 hour 30 minutes. Hour minutes as a pair always meet at 60: 60 minutes make 1 hour, 120 minutes make 2, 180 minutes make 3.
How to write the same span
2:00, 2.0 h, 120 min, and 7,200 seconds are one duration. 7,200 seconds follows from 120 × 60. Pick the unit the form asks for. A timesheet that wants hours does not want 120 in the hour column unless the column is minutes.
On a 24-hour clock, a two-hour block from 13:00 ends at 15:00. On a 12-hour clock, a two-hour block from 1:00 p.m. ends at 3:00 p.m. Same minutes. Different numerals on the face. Common conversions on this page:
60 minutes = 1 hour. 90 minutes = 1.5 hours = 1 hour 30 minutes. 120 minutes = 2 hours. 12 hours = 720 minutes. 24 hours = 1,440 minutes. If you type 120 into a box labelled “hours,” you have just scheduled five days, not a nap. The label on the box is the unit.
24 hours is not 24 × 120
The trap is stacking the wrong factor. 24 hours is 24 × 60 minutes, not 24 × 120. 120 already used the 60 twice. Putting 120 back into a day count would double-count the hour. How many minutes in 12 hour is 720. How many minutes in an hour is 60. How much time is 120 minutes is 2 hours. Those three sentences share the same 60. They do not share the same left-hand number.
A civil day can be 23 or 25 hours where daylight saving time starts or ends. The minute count for that civil date then becomes 1,380 or 1,500 instead of 1,440. The conversion 60 minutes per hour still holds. Only the number of hours in that particular date changed. 120 minutes is still 2 hours on those dates too.
When a recipe, exam, or film lists 120 minutes, set a 2-hour timer. When a travel board lists 90 minutes, set 1 hour 30 minutes. When someone asks how many minutes is 24 hours, answer 1,440 and stop. You do not need a second system of hours to finish the arithmetic.

100 seconds
100 seconds equals one minute forty seconds, or 100 s, or PT1M40S. It is a short duration. It is not 1:00, and it is not a hundred on a digital clock.
13 hour cast
A 13 hour cast writes thirteen hours as a label in front of the word cast. Most people who type it want the actors in the film 13 Hours. The number is a duration, not a clock time.
