Once an audio signal has been digitalized, it has no units and it is treated as a number. You could use dBFS (decibels relative to full scale) as unit, though.

What is the size of a WAV file?
The WAV format is by definition, the highest quality 16-bit audio format. It is also the largest at about 10 MB per minute of CD quality audio. The quality can be sacrificed for file size by adjusting the sampling rate, data width (i.e. 8-bits), and number of channels (up to 2 for stereo).
What values are stored in a WAV file?
Most commonly, they represent sample values as 16-bit signed numbers that represent the audio waveform sampled at a frequency such as 44.1kHz.
How many bytes is a WAV file?
The chunk ID is always "fmt " (0x666D7420) and the size is the size of the standard wave format data (16 bytes) plus the size of any extra format bytes needed for the specific Wave format, if it does not contain uncompressed PCM data. Note the chunk ID string ends with the space character (0x20).
What makes up a WAV file?
WAV files are lossless uncompressed broadcast CD quality music files. Loops can be used to extend a full track or just by itself. WAV loops can also be easily processed with Flash for web animations.
