How to convert pounds(Lb) to ounce(Oz) and Ounce(Oz) to Pounds(Lb) in C#.Net code

[somagunasekaran]

Hi Team, I am working on unit of measure.. Just I want to know that logic part of the C#.Net source code for convert to Lb to Oz and Oz to Lb in drop down. If you are selecting as LB in one of the drop down and one more drop down selecting as a Oz and total converting calculation will be displayed in one of the text box. Please let me know how to convert this logic part. I am struggling now this logic part in drop down. Thanks Somasundaram

1lb = 16oz If you're converting from lb to oz, multiply by 16. If you're converting from oz to lb, divide by 16. (Assuming you're not using Troy pounds/ounces[^].)

There's no real "logic part" in the operation: it's all about identifying what the conversion factor is. I'm just guessing that you're a beginner and this is homework - so I won't explain how I'd do it (it probably involves some bits you haven't got to yet) and suggest that you pick a "base unit" and provide each possible "convertable unit" with a value which converts to that base unit. For example, if you select the kilogram as your base unit, then the conversion factor for 1lb would be 2.20462, and the conversion factor for 1oz would be 35.274 So to convert from "unit a" to "unit b" you multiply the number of items by the "unit b" conversion factor, divide that by the "unit a" convertion factor, and round it to perhaps 2 decimal places. If the number of lb is 6.0, then you would convert to oz by:

6.0 * 35.274 / 2.20462 = 96.0002177246

Rounded, that's 96.00 oz. So all you need to do is write a method which takes the selected unit text, and returns the conversion factor. Then call that twice, and you're pretty much there! Try it: it's simpler than it sounds!

If you are really "working on unit of measure", you should take a moment to consider the longer term; e.g. a "weight structure / class". The weight could have a "native" value, but would have methods for returning different UOMs: all ounces or grams; or pound / kilogram fractions; etc.

public class MyWeight {

public decimal Weight { get; set; }
public UnitOfMeasure Units { get; set; }

public MyWeight( decimal weight, UnitOfMeasure units = UnitOfMeasure.Pounds ) {
this.Weight = weight;
this.Units = units;
}

public decimal InPounds( int decimalPlaces = 0 ) {

  decimal qty = 0M;

  switch ( this.Units ) {
     case UnitOfMeasure.Pounds:
        qty = Weight;
        break;
     case UnitOfMeasure.Ounces:
        qty = Weight \* 0.0625M;
        break;
     case UnitOfMeasure.Kilograms:
        qty = Weight \* 2.20462M;
        break;
     case UnitOfMeasure.Grams:
        qty = Weight \* 0.00220462M;
        break;
     default:
        throw new NotImplementedException( string.Format( "{0} to Pounds.", Units ) );
  }  // end switch:

  qty = RoundUp( qty, decimalPlaces );

  return qty;

}

// Etc.

Be fair, he said it was three years in the field. Very possibly there was no computer in this field. Perhaps there were some sheep.

Even the sheep could have worked it out by now! :laugh:
