128h × 3600s = 460800 seconds
We also know that 1 minute equals 60 seconds. Therefore to get the number of minutes in seconds we need to multiply the amount of minutes by 60. In this case we have to multiply 23 minutes by 60:
23m × 60s = 1380 seconds
Now we have to add both amount of seconds to get the final result:
460800s + 1380s = 462180 seconds
Finally we can say that 128 hr 23 min is equivalent to 462180 seconds:

Units definitions
The units involved in this conversion are hours, minutes and seconds. This is how they are defined:
Hours
An hour (symbol: h, also abbreviated hr) is a unit of time conventionally reckoned as 1⁄24 of a day and scientifically reckoned between 3,599 and 3,601 seconds. In the modern metric system, hours are an accepted unit of time defined as 3,600 atomic seconds. There are 60 minutes in an hour, and 24 hours in a day.
Minutes
The minute is a unit of time usually equal to 1⁄60 (the first sexagesimal fraction) of an hour, or 60 seconds. In the UTC time standard, a minute on rare occasions has 61 seconds, a consequence of leap seconds (there is a provision to insert a negative leap second, which would result in a 59-second minute, but this has never happened in more than 40 years under this system). Although not an SI unit, the minute is accepted for use with SI units. The SI symbol for minute or minutes is min (without a dot).
Seconds
The second (symbol: s, also abbreviated: sec) is the unit of time in the International System of Units (SI), historically defined as 1⁄86400 of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each (24 × 60 × 60 = 86400).
