You can program this function if it does not exists

public float RangeLerp(float value, float istart, float istop, float ostart, float ostop)
    return ostart + (ostop - ostart) * value / (istop - istart);

the code needs a little fix:

( x - ostart ) / ( ostop - ostart ) = ( value - istart ) / ( istop - start )

if you islolate x the return must be:

return ostart + (ostop - ostart) * (value-istart) / (istop - istart);
