The UCUM-LHC Validator and Converter

UCUM Unit Conversions

Convert values from one UCUM unit to another

Enter or select a valid UCUM code for the unit you want to convert:      UCUM codes are case-sensitive

If you are not finding a unit that you think should be there, check the advanced search options to see if you should add a category (or categories) to the search.



Enter the numeric value you want to convert:     Result rounded to decimal digits.


Enter or select the unit that you want to convert to:

You can enter other commensurate units that are not on this list.
  

  

Disclaimer:  Conversion results are for demonstration purposes only. Before relying on the unit conversions produced by this tool it is your obligation to perform your own tests to verify that the results are sufficiently accurate for your purposes.

UCUM Unit Expression Validation

Validate unit expressions one at a time

Enter or select a unit expression to be validated:    

If you are not finding a unit that you think should be there, check the advanced search options to see if you should add a category (or categories) to the search.


  

  

Validate all unit expressions in a CSV file

We can validate unit expressions in a comma separated values file on your system.

  • Use the browse button below to select the file.
  • You will then be asked for the name of the column that contains the expressions to be validated. (Your file must include column headers).
  • A copy of your file will be created that includes three additional columns at the end, confirming what expression was validated, the validation results, and any relevant notes.
  • You will be asked where you want the file saved. You may change the name of the output file at that time.
  • Note that this will only validate unit expressions. Although prefixes used with a unit code, e.g., "kL" (kiloliter), are recognized as prefixes ("k" for kilo) modifying a unit code ("L" for liter), a prefix submitted by itself, e.g., "E" (exa) will result in an "invalid unit code" return.
