Yes, converting from a traditional IRA to a Roth IRA is often a wise decision if you are in a low tax bracket and will stay in a low tax bracket after the conversion. Doing this will reduce future required minimum distributions (RMDs) from your traditional IRA. 

Note though, that the taxable portion of your social security benefits may increase as a result of the conversion, so you may want to run some figures to see how you land. Here are some tools you can try. Note that these two tools are currently not set up yet for 2025, but that should change in the next month or two.
