Match the state
Use melted butter for melted coconut oil and softened butter for solid coconut oil.
The important exception
Coconut oil is solid below roughly 24°C, so it behaves structurally more like butter than liquid oils do. For volume substitutions, a 1:1 swap is usually the useful starting point.
Coconut oil and butter are both solid at typical room temperature, so the engine uses a 1:1 volume rule.

Warm kitchens can liquefy coconut oil, changing how it creams and sets.
Refined coconut oil is mild; virgin coconut oil contributes a clear coconut aroma.
