The exact relationship
1 TON = 1,000,000,000 nanoton (10^9). To convert TON to nanoton you multiply by 1,000,000,000. So 1 TON is 1000000000 nanoton and 0.25 TON is 250000000 nanoton. The result is always a whole number, since nanoton is the indivisible base unit.
Where you hit this in real work
When you send a message or transfer on TON, amounts are expressed in nanoton rather than TON. Sending 2 TON means setting the value to 2000000000 nanoton. Converting the human TON figure into nanoton gives the integer the API expects.
