I probably should know how to do this from high school math but......
Is there a rough estimate of distance from an indoor workout?
I know: RPM, time, wheel (700).

"700" is a type, not a measurement.

You could calculate this, but it won't really matter. I would ask: how do you know RPM (I assume cadence) w/o knowing speed? Speed x time = distance. Thankfully my cadence/spedometer is rear-mounted, so it works on my Road Machine. With that, there's an approximate power curve, so a speed to power translation, within reason, is possible.

It would be much more useful to approximate how much power you put out, or use a HR monitor. The speed you work at indoors will probably not translate to the speed you do outside.

It would be possible to determine your "speed" if you knew your cadence and what gear you were in, but the resulting answer would be meaningless.

Maybe a different question then.... now that I have moved indoors to trainer, how do a equate my workout to what I do on the road? I guess limiting my perspective to miles is no the way the continue. I do no have a power tap.

Time and intensity. If you have a heart rate monitor you can use that or you can just go by your perceived effort. E.g. "really hard" or "easy spin."
