Our Time Calculator can quickly give you the answer. To use it, follow these simple steps:
How long is 90 minutes? What is 90 minutes in hours?
Because 1 minute is equal to 1/60 hours, to convert 90 minutes to hours we simply multiply 90 minutes by 1/60 hours
Thus, 90 minutes in hours = 1.5 hours.
Conclusion: there is 1 full hour and 30 minutes in 90 minutes.
The answer is a decimal, so we can convert it back into hours and minutes. You can use a scientific calculator with a degrees function as described above, or you can do a bit more maths. We can convert 0.5 hours into minutes. 1.5 hours is therefore 1 hour and 30 minutes.
1.5 hours.
1.5 hours is equal to 90 minutes. Yes, similar to asking an engineer the meaning of 1 meter and asking an artist how can you express the meaning of 1 m/s.
