The format of the response can differ depending on set flags.

This chapter describes flags that can be applied to units and parts of resulting JSON which they are responsible for. If you specify several flags, then parts will be gathered into one JSON.

All flags are only used in DEC format.

Unit flags:

Flag - 0x00000001

{
	"mu":<uint>,	/* measure units: 0 - si, 1 - us, 2 - imperial, 3 - metric with gallons */

}

Flag - 0x00000002
