  • If the input data types are incorrect, CONVERT returns the #VALUE! error value.

  • If the unit does not exist, CONVERT returns the #N/A error value.

  • If the unit does not support a binary prefix, CONVERT returns the #N/A error value.

  • If the units are in different groups, CONVERT returns the #N/A error value.

  • Unit names and prefixes are case-sensitive.

This is an example of how a formula uses CONVERT.
