Skyrim time is 20 times real time so:
Minutes
1 second = 20 seconds
*3
60 seconds
and whatever we do to one number, we have to do to the other
Therefore: 3 seconds = 1 minute
Hours
Method one
1 minute = 20 minutes
*3
and whatever we do to one number, we have to do with the other
Therefore: 3 minutes = One hour
Method two
3 seconds = 1 minute
60 minutes in an hour so:
3 * 10 = 30
30 * 5 = 150
150 + 30 = 180
180 seconds = 3 minutes
Therefore: 3 minutes = 1 hour
Days
3 minutes * 4 = 12 minutes
3 minutes * 10 = 30 minutes
30 minutes * 2 = 60 minutes {1 hour}
1 hour + 12 minutes = 1 hour 12 minutes
