Gauging vs. Gaging
This is a variant-preference task, not a false correct/incorrect binary. Cambridge records US “gage” as a variant of “gauge,” while Merriam-Webster lists “gauging also gaging” and describes gauge as overwhelmingly preferred in general use. Specialized technical house usage may still choose gage/gaging.
For general writing, prefer “gauging interest.” “Gaging” is attested as the -ing form of the less-common variant “gage,” so it is not automatically a typo, but Merriam-Webster says “gauge” is by far the preferred spelling in general usage.

Quick tests
General-prose test
Is this ordinary edited writing with no specialist house convention?
If yes: Prefer “gauging.”
If no: If the document deliberately uses technical “gage,” check that convention before changing it.
Caveat: Check the exact meaning and context before applying the pattern mechanically.
Meaning test
Does the verb mean measure, estimate, or judge interest/reaction?
If yes: Gauge/gauging is the normal general-use spelling.
If no: Choose a different verb if the intended meaning is not measure/estimate/judge.
Caveat: Check the exact meaning and context before applying the pattern mechanically.
Examples
We are gauging interest before scheduling a second session.
“Gauging” is the preferred general-use spelling for judging interest.
The survey is designed to gauge how customers will react.
Cambridge records gauge for judging people’s feelings or reactions.
A technical manual may retain “gaging” if its established terminology uses the variant “gage.”
The alternate form is attested, so context can justify it even though general prose strongly prefers gauging.
Further guidance
General Usage
Use “gauging” in ordinary edited prose: “gauging interest,” “gauging demand,” “gauging the reaction.”
Preference
Merriam-Webster describes gauge as by far the preferred spelling in general usage, and Cambridge heads the entry under gauge while noting US gage.
Technical Boundary
If a technical field, product documentation set, or house style deliberately uses “gage,” retain that convention consistently rather than applying a blanket correction.
Variant Status
“Gaging” is a recognized alternate form, not an invented spelling; it follows the less-common variant verb “gage.”
