There a re 1,000 mSats in a Sat.
There are 2,100,000,000,000,000,000 mSats in the Bitcoin protocol of Layer 2. That's 2.1 Quintilian.
There are 2,100,000,000,000,000 Sats to play with on chain. That's 2.1 Quadrillion.
lightning can go lower than msats, it's just a unit attached to an invoice, see BOLT11:
Human-Readable Part
The human-readable part of a Lightning invoice consists of two sections:
- prefix:
ln
+ BIP-0173 currency prefix (e.g.lnbc
for Bitcoin mainnet,lntb
for Bitcoin testnet,lntbs
for Bitcoin signet, andlnbcrt
for Bitcoin regtest)amount
: optional number in that currency, followed by an optionalmultiplier
letter. The unit encoded here is the 'social' convention of a payment unit -- in the case of Bitcoin the unit is 'bitcoin' NOT satoshis.The followingmultiplier
letters are defined:
m
(milli): multiply by 0.001u
(micro): multiply by 0.000001n
(nano): multiply by 0.000000001p
(pico): multiply by 0.000000000001
This means that a lightning invoice for 100k sats starts with
lnbc1m
because 1 mBTC is 100k sats.
