What is the numerical definition of a Satoshi relative to a BTC? In previous definitions of a Satoshi, I only saw the decimal place in front of the 0's and the #1 (.0001), but no 0's after the #1 and that's confusing to me. If however you also put the 0's behind the #1 it makes much more sense to me: Ex. .0000100000 BTC = 100,000.00 Satoshis. I can now see the number value of Satoshi based on the number of 0's behind the #1!

1BTC = 100,000,000.00 Satoshi, is this a accurate understanding?
Satoshis are indivisible on the Bitcoin blockchain. Therefore, it doesn't make any sense to add a decimal point or digits after the decimal point to satoshi values.

The conversion is:

100,000,000 satoshi = 1 BTC

or

1 satoshi = 0.00000001 BTC
