This VBA macro converts the value specified in system units (meters) into the fraction inches with specified denominator.

For example the value of 0.112713 with denominator 16 would be converted to 4 7/16”

Configure the parameters as per the settings below:

Const DENOMINATOR As Integer = 16 'denominator value
Const ROUND_TO_NEAREST_FRACTION As Boolean = True 'True to round to nearest fraction, False to not

The result and available options are equal to the dimension property manager page in SOLIDWORKS

Const DENOMINATOR As Integer = 16
Const ROUND_TO_NEAREST_FRACTION As Boolean = True

    Debug.Print ConvertMetersToFractionInches(0.112713, DENOMINATOR, ROUND_TO_NEAREST_FRACTION)
    
End Sub

    swUserUnits.SpecificUnitType = swLengthUnit_e.swINCHES
    
    swUserUnits.RoundToFraction = round
    swUserUnits.FractionValue = denom

    ConvertMetersToFractionInches = swUserUnits.ConvertToUserUnit(value, True, True)
