Variable Definitions
Quantity in original time unit
Conversion factor to base seconds
Conversion factor from base seconds to target unit
Step-by-Step Practical Example
Identify source factor: 1 day = 86,400 seconds.
Multiply input by factor: 2.5 x 86,400 = 216,000 seconds.
Identify target factor: 1 minute = 60 seconds.
Divide seconds by target factor: 216,000 / 60 = 3,600 minutes.
