In practical use, it is common to round the calculated metric number. With that, there are several possibilities.

:By {{tlf|Convert}} default, the conversion result will be rounded either to precision comparable to that of the input value (the number of digits after the decimal point—or the negative of the number of non-significant zeroes before the point—is increased by one if the conversion is a multiplication by a number between 0.02 and 0.2, remains the same if the factor is between 0.2 and 2, is decreased by 1 if it is between 2 and 20, and so on) or to two significant digitsfigures, whichever is more precise. An exception to this is ''rounding temperatures'' (see [[#Rounding temperatures|below]]).

===Round to a given precision: ''use a {{para|precision number|}}''===Specify the desired precision with the ''fourth unnamed parameter'' (or third unnamed parameter if the "convert to" parameter is omitted; or fifth unnamed parameter if a range is specified; or fourth unnamed parameter again if a range is specified and the "convert to" parameter is omitted; needs to be replaced with a "precision" named parameter). The conversion is rounded off to the nearest multiple power of {{frac|1/10}} to the power of this number. For instance, if the result is 8621 and the round number is "-2", the result will be 8600. If the result is "234.0283043" and the round number is "0", the result will be 234.

(1) and (2) seem to belie the fact that a {{convert|0.1|C-change|F-change|disp=x| is a |abbr=off}}, and make the 32 degrees difference shown in (1) begin to seem off somehow.Result (1) seems off until you set the [[significant figures]] yourself with {{para|sigfig}}::{{#invoke:DemoTemplate|convert|10000|C|sigfig=5}}or you set the precision ''positionally'', relative to the decimal point (zero being ''at'' the decimal point)::{{#invoke:DemoTemplate|convert|10000|C|0}} The precision of the input number in example (2) is six, so the precision of the Fahrenheit output is, whereas before, Kelvins had determined it to be three. Examples (3) and (4) show how this can be hidden and generate questions, but it occurs there because the Kelvins conversion generated two fractional parts. (Before it was the input number that generated the fractional part.) In example (3) the three input digits converted into five significant output digits because of the two digits after the decimal point, generated by the Kelvins conversion. This happened again in (5), but in (6) decimal fractions were neither given as input nor induced by the Kelvins conversion. ===Rounding input===There is limited support for rounding the displayed ''input'' number. The rounding takes place ''after'' conversion, so the output is based on the full-precision input. This is useful when the input is produced by {{tlc|&#35;expr:}} or otherwise available to a higher precision than is usefully displayed, and it's desirable to avoid double-rounding. To round the input to a specified number of digits after the decimal point, use one of the parameters:* {{para|adj|ri0}}* {{para|adj|ri1}}* {{para|adj|ri2}}* {{para|adj|ri3}}Note that there is no {{para|adj|ri-1}}{{nay}} or similar for rounding above the decimal place. Neither is there support for significant figures, multiples of 5, or any other output-rounding feature. The default precision is computed based on the input, so an explicit output precision must usually be supplied:* {{tlc|convert|4.14159|mi|km|adj{{=}}ri0}} → {{convert|4.14159|mi|km|adj=ri0}} {{nay}} (precisions are mismatched)* {{tlc|convert|4.14159|mi|km|0|adj{{=}}ri0}} → {{convert|4.14159|mi|km|0|adj=ri0}} {{aye}} In this case, if the input were rounded before conversion, a different result would be obtained:* {{tlc|convert|<nowiki>{{#expr:4.14159 round 0}}</nowikismall>|mi|km|0}} → {{convert|{{#expr:4.14159 round 0}}|mi|km|0}} {{nay}} (double rounding)

===Spelling of unit name: international UK ''metre'' or US ''meter''?===Default spelling of units is in the en (generic) locale-UK. To show en-US spelling, use {{para|sp|us}}::<code><nowiki>{{convert|1|m|ft}}</nowiki></code> → {{convert|1|m|ft}}—-- ''default''

===Using an SI prefix: ''gigametre (Gm)'', or ''micrometre (&#x03BC;m)''==={{Sidebar metric prefixes (small)}}Units can have an [[metric prefix|SI prefix]] like <code>G</code> before the unit: <code>Gm</code>, and <code>giga</code> before the name: <code>gigametre</code>. These are plain multiplication factors. To illustrate, these are trivial calculations (from metre meter to metremeter), showing the multiplication factor:

The prefix can be added before the SI unit (here: unit <code>m</code> for metremeter):

* <code>&#x03BC;mμm</code>: {{convert|12|μm|mm|abbr=on}}* <code>um</code>: {{convert|12|um|mm|abbr=on}} (letter "u" can be used for "&#x03BC;μ" here)

* <code><nowiki>{{convert|12000|mi||Mm|abbr=on}}</nowiki></code> → {{convert|12000|mi|Mm|abbr=on}}

As an exception, the non-SI unit "inch" can have the "&#x03BC;μ" prefix too:)* <code><nowiki>{{convert|12|&#x03BC;mμm|μin|abbr=on}}</nowiki></code> → {{convert|12|μm|μin|abbr=on}}

===Thousands separator: ''1,000 mi'' and ''1000 mi''===In input, a comma for thousands separator is accepted. A gap (space) is not. In output, by default, the thousand separator is the comma:*<code><nowiki>{{further informationconvert|Help:Convert units#SI prefixes1,234,567|m|ft}}</nowiki></code> → {{convert|1,234,567|m|ft}}*<code><nowiki>{{convert|1,234,567|m|ft}}</nowiki></code> → {{convert|1,234,567|m|ft}}*<s><code><nowiki>{{convert|1 234 567|m|ft}}</nowiki></code> → {{convert|1 234 567|m|ft}}</s>

For the [[Help:Table/Manual tables|wikitable]] structure, there are three two options: add a line-break, split the result over columns and make the table sortable. ===Enforced line break==={{para|disp|br}} adds a line-break and omits brackets. {{para|disp|br()}} adds a line-break and does add brackets to the converted value. This may be useful Show numbers only in tables:{| class=wikitable! {{para|disp|br}} !! {{para|disp|br()}}|-|{{convert|100|km|mi|disp=br}}|{{convert|100|km|mi|disp=br()}}|} ===Table columns in a table===Using {convert} in a table cell, with {{para|disp|table}} splits the result over two (or more) columns. By default units are not included in the table, however, they can be added using the {{para|abbr|}} parameter.
