Alternative to starting enum values with a number I have an enum like the following:

enum MeasurementBandwidth
{
    Hz1 = 1,
    Hz3 = 3,
    Hz10 = 10,
    ...
}


But I do not like the Hz1, and 1Hz is not valid as it starts with a number.

Does anyone have an idea how to solve this "more elegant"?

Why I am doing this:  

I have an API, which offers a method like the following:  

public double MeasureInput(double frequency, MeasurementBandwidth bandwidth) { /*...*/ }


And the bandwidth only has a few possible values which can be used and I want to make it as easy as possible for the "user" to choose a valid one. Using an enum was the best solution I came up with, as it is directly visible from the parameter type, what values are valid.
public enum Hertz{
    none = 0,
    Hz= 1,
    KHz = 1000, 
    MHz = 1000000,
    GHz = 1000000000
}

public static class Frequency{
    public static int Hz(this int frequency){
        return frequency;
    } 

    public static int KHz(this int frequency) {
        return  frequency * (int)Hertz.KHz;
    }

}


client code:

int freq = 10.Hz();
int faster = 10.KHz();
int thousandsOfGigahertz = 234.KHz().GHz();
