What is Unit conversion?

Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.

The 50 cents per minute can be converted to dollars per hour as,

50 cents per minute

= 50 cents / 1 minute

Since 1 dollar has 100 cents and 1 hour has 60 minutes, therefore,

= (50/100)dollar / (1/60) hour

= (50×60)/100 dollars per hour

= 3,000/100 dollars per hour

= 3 dollars per hour

Hence, 50 cents per minute to dollars per hour is 3 dollars per hour.
