Length of the audio can be expressed in time. Example,this audio is 30 second long.

It can also be express as the number of sample. Example the audio has 14000 samples

Yes.

The sampling frequency, ‘Fs’ is in units of samples/second, so use that to convert them:

Number of samples = Fs * time

Time = number of samples / Fs
