help with converting currencies for commissions

[steep sigil]

my country uses a different currency then usd (aud) and im not sure which currency i should set my commission prices for. would it be better to have them set by usd prices as americans are most likely to be looking at my art? if i were paid ten dollars by an american that would only be worth about 6 bucks in my country this is confusing me so much am i just overthinking it????? idk how money works man

also if this is too unrelated to art im sorry
