Just for reference, Bitcoin does not allow for a quantity of BTC smaller than a satoshi, because the calculation for the total amount of BTC is an integer amount of satoshis (i.e. 2,100,000,000,000,000 satoshis). See this file and compare lines 15 and 26.
On LN you can use msats. Actually on LN the standard unit is msats.
But onchain, yes, the unit is sat.
