The exact relationship

1 BTC = 100,000,000 satoshi (10^8). To convert BTC to satoshi you multiply by 100,000,000. So 1 BTC is 100000000 satoshi and 0.001 BTC is 100000 satoshi. The result is always a whole number, since satoshi is the indivisible base unit.

Where you hit this in real work

When you build a transaction or set an amount for a Bitcoin Core RPC call, values are expressed in satoshi rather than BTC. Converting a human BTC figure into satoshi gives the integer the wallet or node expects, and keeps the calculation free of rounding errors.
