The recipient's Nostr pubkey is used directly as the internal key of a BIP-341 P2TR output, with no mathematical conversion. The output key is produced by the standard BIP-341 key-path-only tweak (no script tree), and encoded as bech32m (BIP-350) with human-readable prefix bc. Every Nostr pubkey therefore has exactly one corresponding mainnet Taproot address, and anyone can compute it from the pubkey alone.
So, take your npub, follow the steps in the above paragraph and you will get a taproot address. Then check it on a block explorer. Consider using tor or a VPN at least.
