A precision value is entered after the conversion information. For example, |2 gives a result that is rounded to two decimal places, while |-2 rounds to the nearest 100 so that two zeroes occur at the end of the number. This message will only appear if warnings have been enabled.

Precision too large

{{convert|123|m|ft|2}}→ 123 metres (403.54 ft){{convert|123|m|ft|200}}→ [convert: precision too large]
Generally there is no reason to use a precision of more than a few decimal places, however, larger values may be used. The error shown occurs if the requested precision is higher than the maximum supported by the server.
A negative precision rounds to the nearest 10 (parameter |-1), or nearest 100 (|-2), or nearest 1000 (|-3), etc. A large negative precision produces a zero output.
{{convert|123|m|ft|-2}}→ 123 metres (400 ft){{convert|123|m|ft|-200}}→ 123 metres (0 ft)
Using a very small input value can cause the default precision to exceed the limit (1.234e-200 is 1.234×10−200). For such very small values, it is better to use the |sigfig= option.
{{convert|1.234|m|ft}}→ 1.234 metres (4.05 ft){{convert|1.234e-200|m|ft}}→ [convert: precision too large]{{convert|1.234e-200|m|ft|sigfig=3}}→ 1.234×10−200 metres (4.05×10−200 ft)

A fraction denominator can be specified to display results with a fraction where appropriate. For example, |frac=8 specifies that the value should be rounded to the nearest eighth, and that a fraction should be included if necessary. A fraction denominator must be a whole number with value 2 or more. This message will only appear if warnings have been enabled.

The number of significant figures in the result can be specified. For example, |sigfig=2 requests two significant figures. The number of significant figures must be a whole number with value 1 or more. This message will only appear if warnings have been enabled.

{{convert|123|m|ft|sortable=on}}→ 123 metres (404 ft){{convert|123|m|ft|sortable=out}}→ 123 metres (404 ft)*
The option |sortable=on outputs a hidden sort key for use in a sortable table. The option |sortable=out is now the same as |sortable=on, and the latter should be used. See deprecated options for information regarding which options should be used to replace those that are being phased out.

The option |sp=us specifies that US spelling should be used ("meters" instead of "metres"). However, |sp= has no effect as no value is specified. This message will only appear if all warnings have been enabled.

{{convert|123|m|ft|abbr=off}}→ 123 metres (404 feet){{convert|123|m|ft|abr=off}}→ ᱪᱷᱟᱸᱪ:Convert/warning
The option |abbr=off specifies that abbreviations are off, that is, unit names will be used instead of symbols. By contrast, |abr=off is ignored because "abr" is not the name of an option. This message will only appear if warnings have been enabled.

{{convert|123|psi|Pa}}→ 123 pounds per square inch (850,000 Pa){{convert|123|psi|ha}}→ 123 pounds per square inch ([convert: unit mismatch])
It is only possible to convert between units that have the same type. For example, psi and Pa are each of type "pressure" so a psi value can be converted to Pa. However, a psi value cannot be converted to a unit of a different type, such as ha (hectare) which has type "area".

Some unit codes are not supported; using them results in an message indicating that a different unit code should be chosen.

Some units can only be used as outputs. For example "C F" displays a temperature in Celsius and Fahrenheit. Such a unit cannot be used with an input value, because, for example, there is no such temperature as "123 C F". Some output combinations are predefined—"C F" is one example, and "mi km" (miles and kilometres) is another. It is also possible to construct an output combination by joining unit codes with "+". However, individual units have to be specified, and an output combination cannot be used.

{{convert|input=P123}}→ [convert: wikidata problem]
An unexpected error occurred while attempting to use the Wikidata modules to read property or item information. This error should not occur; the above is a simulation of what would be displayed if, for example, the Wikidata modules were not available, or if they contained an error.

{{convert|input=whatever}}→ [convert: invalid input]
Convert is configured to display any input text without error if a conversion fails, so this error should not occur. The above is a simulation of what would be displayed if convert were configured to show problems when a conversion was not possible.
The following examples use the input parameter. The unit mV is known to convert, but since no useful conversion is possible, there is no output. There is no boxes unit, so the input is displayed as given. The final example follows the same rule because P123. is not a valid property identifier.
{{convert|input=12 mV}}→ 12 mV{{convert|input=12 mV|abbr=on}}→ 12 mV{{convert|input=12 boxes}}→ 12 boxes{{convert|input=P123.}}→ P123.
