The exact relationship
1 TRX = 1,000,000 sun (10^6). To convert TRX to sun you multiply by 1,000,000. So 1 TRX is 1000000 sun and 0.5 TRX is 500000 sun. The result is always a whole number, since sun is the indivisible base unit.
Where you hit this in real work
When you build a TRON transaction or call the HTTP API, amounts are expressed in sun rather than TRX. Sending 10 TRX means setting the amount to 10000000 sun. Converting the human TRX figure into sun gives the integer the node expects.
