Template talk:Convert

Frequently asked questions

Q: When using {{convert}} why does the answer sometimes seem a bit off?

A: This template takes into account the precision of the supplied value and generally rounds the output to the same level of precision. If you need to change from the default output precision, see rounding.

Note: This can cause whole numbers that end in one or more zeroes to be converted less accurately than expected.

Q: What are all the possible units (kg, lb, m, cm, ft, in, °C, °F, km, mi, nmi, mph, km/h, and so on)?

A: See Help:Convert units for an introduction and Module:Convert/documentation/conversion data for the complete list.

Q: I've been using Convert for some time and am pretty comfortable with its basic features. Does it have other features which it would be worth my while to learn about?

A: Almost certainly. Start with Help:Convert.

Multiple values, shorter abbreviation?

Is it possible to display a shorter version than

{{convert|149.6x71.5x8.25|2|mm|2}}

149.6 by 71.5 by 8.25 millimetres (5.89 in × 2.81 in × 0.32 in)

Or?

{{convert|149.6x71.5x8.25|mm|2|abbr=on}}

149.6 mm × 71.5 mm × 8.25 mm (5.89 in × 2.81 in × 0.32 in)

In some infoboxes (eg, {{Infobox mobile phone}}), where space is limited, it is desired to list the dimensions of some object, and its conversion, but it seems unnecessary to list the “mm” and the “in” three times. I might be missing something, but I would like an option to display something like:

149.6 × 71.5 × 8.25 mm (5.89 × 2.82 × 0.32 in)

Use xx instead of x.

{{convert|149.6xx71.5xx8.25|mm|2}} gives 149.6 × 71.5 × 8.25 mm (5.89 × 2.81 × 0.32 in)

Beware that this technically violates MOS:UNITSYMBOLS. |by| is an option that obeys the MOS (but looks clumsier).

{{convert|149.6|by|71.5|by|8.25|mm|2}} gives 149.6 by 71.5 by 8.25 mm (5.89 by 2.81 by 0.32 in) Stepho talk 23:49, 6 November 2024 (UTC)[reply]

Thank you! I might actually ask at MOSNUM, because this feels like an oversight (for use in small spaces), and I’d like to standardise this across a lot of infoboxes. — HTGS (talk) 00:06, 7 November 2024 (UTC)[reply]

Troy weight

I'm not sure if this is the right place to discuss this, but is it possible to integrate troy weight into this template? Basically another obscure, antiquated unit of mass that still sticks around out of tradition in the precious metals industry. TheTechnician27 (Talk page) 12:23, 10 November 2024 (UTC)[reply]

@TheTechnician27: It's already provided, e.g. {{convert|1|ozt|g|3}} → 1 troy ounce (31.103 g). See full list of mass units. --Redrose64 🌹 (talk) 15:48, 10 November 2024 (UTC)[reply]

@Redrose64: Oooh, thank you! I was trying to use 'oz t' with no success. TheTechnician27 (Talk page) 17:26, 10 November 2024 (UTC)[reply]

Indian numbering system: lakhs and crores

Moved from Module talk:Convert. Johnuniq (talk) 01:45, 19 November 2024 (UTC)[reply]

I request that we enhance the module to include lakhs and crores.

The Indian numbering system is the main nomenclature used in South Asia to name large numbers. From the lead:

The terms lakh or 1,00,000 (one hundred thousand, written as 100,000 in Pakistan, and outside the Indian subcontinent) and crore or 1,00,00,000 (ten million, written as 10,000,000 outside the subcontinent) are the most commonly used terms in Indian English to express large numbers in the system.

This is a dimensionless unit, or if you wish, the units are integers. (Hence if implemented, the data item in 'all_units' at Module:Convert/data could be named ["ins"] for 'Indian numbering system'). Note also the main pattern of comma-separation into groups of two and three digits, not just three.

These terms should be converted to standard English terms, mostly with the term million, except for values up to 9 lakh, which could be 900,000. Sample usage in articles:

lakh – 6,914 articles
crore – 10,809 articles

The plural sometimes has the -s, and sometimes doesn't; so both '2 lakhs' and '2 lahk' are seen; same for crore(s).

This arose at the Rfc at Wikipedia talk:Manual of Style/Dates and numbers, where in my !vote (diff) I called for using template {{Convert}}, only to realize after the fact that the template will not handle it. This conversion is badly needed, as it will resolve a sore point about usage of lakhs and crores in many articles. Thanks, Mathglot (talk) 23:46, 18 November 2024 (UTC)[reply]

Earlier discussions.

I have not yet examined the RfC at WT:Manual of Style/Dates and numbers#RfC Indian numbering conventions. The above discussions point out that lakh and crore are not units. They are like million which is also not a unit. However, if convert could do something useful that is not provided by {{lakh}} and {{crore}}, it could be investigated.

The {{lakh}} and {{crore}} templates make more sense than overloading {{convert}}. Stepho talk 23:07, 19 November 2024 (UTC)[reply]
