Converting 1e to 2e Content

[Perses13]

How different is converting Starfinder 1e content to Starfinder 2e from converting PF1 content to PF2?

I've used this conversion tool from PF2Easy before to convert PF1 content for skill check DCs and was wondering if the math for Starfinder 1e was close enough to Pathfinder 1e's math make it still useful.

SF1 skill DCs tend to be 10 or 15 + 1.5*level. Since those are formulae, you can convert them using that.

PF2E/SF2E skills follow a formula as well, which should help.

In their case the formula is 14 +(level)*1.3, with no rounding.

Interesting thanks.

If I match up the formulas, it sounds like a rough conversion formula is (13/15)*[SF1 DC] +1 = [SF2 DC] (rounded to the nearest integer). So a DC 15 check would be DC 14, DC 20 would be DC 17, etc, DC 30 would be DC 27, etc.

This is part art, part science, and I imagine adventures don't always follow the guidance, but this should be good as a baseline, thanks.

A quick followup question about circumstantial bonuses. How big did they tend to be in Starfinder 1e? I've seen reference to a +4 circumstance bonus and I'm wondering if I ran that adventure if I should be reduce that to a +1 or =2.
