To convert bytes/second to STM-4 (signal), one essential parameter is needed and this parameter is Unit Value.
The formula for converting bytes/second to STM-4 (signal):
1 Byte/second = 1.2860082304e-8 STM-4 (signal)
Let’s solve an example;
Find the conversion of bytes/second to STM-4 (signal) when the unit value is 20.
1 Byte/second = 1.2860082304e-8 STM-4 (signal)
Then,
20 Bytes/second = (20 x 1.2860082304e-8) STM-4 (signal)
20 Bytes/second = 2.5720164608e-7 STM-4 (signal)
Therefore, the STM-4 (signal) is 2.57e-7.
