Hyperbolic Time Chamber converter
One day outside is one year inside. Pick your units and it converts as you go.
The ratio
Everything here follows from one rule: one day in the outside world is one year inside the chamber, a ratio of 365 to 1.
So an hour outside is a little over fifteen days inside. A minute outside is just over six hours inside. And the canonical two-day training stint is two years of subjective time, which is why anyone using it comes out noticeably older than everyone waiting.
| Outside | Inside |
|---|---|
| 1 minute | 6 hours 5 minutes |
| 1 hour | 15 days 5 hours |
| 1 day | 1 year |
| 2 days | 2 years |
| 1 week | 7 years |
A note on the arithmetic
The year is taken as 365 days, which is the figure the source material uses and the one anybody checking this will have used too. Adding a leap day would change every answer by a fraction of a per cent and disagree with every other reference, which is a poor trade for accuracy nobody asked for.
There is a second rule in the source - that a person may only spend two days of outside time inside across their life - but that is a limit rather than a conversion, so it is not modelled here.
