From seconds to minutes:
1 minute/60 seconds
For 90 seconds:
(90 seconds)*(1 minute/60 seconds)=1.5 minutes
To convert 70 minutes to seconds, you multiply the number of minutes by the conversion factor of 60 seconds per minute. Therefore, 70 minutes × 60 seconds/minute equals 4,200 seconds. Thus, 70 minutes is equivalent to 4,200 seconds.
To convert minutes to hours, you would use the conversion factor of 1 hour = 60 minutes. Therefore, to convert minutes to hours, you would divide the number of minutes by 60. For example, if you have 120 minutes, you would calculate 120 ÷ 60 = 2 hours.
365 days in a non-leap year 24 hours in a day 60 minutes in an hour 60 seconds in a minute 365 x 24 x 60 x 60 = 31,536,000 seconds in a year. Divide 1 by 31,536,000 gives 1 second is .00000003170979 years
The conversion factor is 0.1
The conversion factor is 0.91
you divide by 60. 135/60 is 2.25 minutes.
To convert 70 minutes to seconds, you multiply the number of minutes by the conversion factor of 60 seconds per minute. Therefore, 70 minutes × 60 seconds/minute equals 4,200 seconds. Thus, 70 minutes is equivalent to 4,200 seconds.
One hour = 3600 seconds
Multiply by 3600 1 hour = 3600 seconds
You do not want to change the dimension, just how you express the quantity of the dimension (in different units). Therefore, the conversion factor must be dimensionless. So if your dimension is time, for example. A certain amount of time has passed, say 300 seconds. The amount of time is the same, regardless of what units you express it in. 60 seconds = 1 minute. Divide both sides of this 'equation' by (60 seconds) and you have: 1 = (1 minute)/(60 seconds). So if you multiply 300 seconds by [(1 minute)/(60 seconds)], it is the same as multiplying by 1, which is dimensionless. In this example: (300 seconds)*(1 minute)/(60 seconds) = 5 minutes. So, 300 seconds is the same as 5 minutes, and both are expressions of the same amount of time.
Minutes is time, kilometers is a distance. There's no conversion factor between them.
To convert minutes to hours, you would use the conversion factor of 1 hour = 60 minutes. Therefore, to convert minutes to hours, you would divide the number of minutes by 60. For example, if you have 120 minutes, you would calculate 120 ÷ 60 = 2 hours.
60 minutes = 1 hour Just divide the minutes by 60 to get hours
15 seconds x 1 hour/3600 seconds
