npm install iobroker-adapter-helpersUsage of units and exponents:
Every unit has a base, this base has the exponent 0. Example meter: `{"unit": "m", "exponent": 0}
With the exponent it is simple to convert the given unit in to a higher or lower unit.
This conversion is done with the function Math.pow(10, exponent).
`
const value = 1000 //unit mm
const baseExp = -3; //exponent for mm
const expectedExp = -2; //exponent for cm
console.log( ( value * Math.pow( 10, (baseExp - expectedExp) ) + ' cm' ); //output 100 cm
