__NOTOC__  

## Purpose
The purpose of this template is to automatically convert and format currency from Indian Rupees to other currencies (United States Dollars by default) applying adjustment for inflation where appropriate. Rates of exchange and inflation must be manually copied by editors therefore the template's output does not necessarily reflect the present exchange rates or price indices but, rather, reflects the rates and indices at the time of the last update.  

## Usage
<code></code>  

## Parameters
A description of the template's parameters are listed below.  

| <code>**rupee_value**</code> | mandatory | The value, in Indian Rupees, that needs to be converted. The template will not accept pre-formatted values (i.e. 1,234). |  |
| --- | --- | --- | --- |
| <code>**currency_formatting**</code> | optional | Used to represent larger numbers. Available options are as follows.
* <code>k</code> &ndash; to represent thousand(s)
* <code>m</code> &ndash; to represent million(s)
* <code>b</code> &ndash; to represent billion(s)
* <code>t</code> &ndash; to represent trillion(s)
* <code>l</code> &ndash; to represent lakh(s)
* <code>c</code> &ndash; to represent crore(s)
* <code>lc</code> &ndash; to represent lakh crore(s)

* **Brackets in the sense may be singular (or) plural**. |  |
| <code>**rounding_digits**</code> | optional | Used to round significant digits. Negative values (-2, -3) can be used to round values to the nearest hundred or thousand, etc. A value of "0" will drop paise or cent values from the converted number. By default the conversion will be rounded to two significant figures.
Refer to the Examples section below for more examples. |  |
| <code>**lk**</code> | optional | This parameter gives you the option of internally linking currency names (rupees and paise) and/or number names (lakh and crore). By default, the parameter is set to "off" (i.e. it is set not to link). Available options are as follows.
* <code>on</code> &ndash; to link "rupee"/"paise" and "lakh"/"crore"/"billion"
* <code>r</code> &ndash; to link "rupee"/"paise"
* <code>b</code> &ndash; to link "billion"
* <code>t</code> &ndash; to link "trillion"
* <code>l</code> &ndash; to link "lakh"
* <code>c</code> &ndash; to link "crore"
* <code>lc</code> &ndash; to link "lakh" and "crore"
On by default. |  |
| <code>**year**</code> | optional | This parameter allows for inflation. Historic rupee values will be inflated to current values then converted. |  |
| <code>**to**</code> | optional | This parameter allows for conversion to various different currencies (and some combinations). Currently, the US (default), Canadian, Australian and New Zealand dollars, the euro, the pound sterling, Pakistani rupee and the Bangladeshi taka are supported. |  |
| <code>**mode**</code> | optional | This parameter controls the output mode. Setting it to blank or omitting it results in the default mode. Setting it to <code>historical</code> allows conversion using historical exchange rates. The <code>year</code> parameter must be between 1970 and 2018 in historical mode. | } |

## Updating
It is important to keep the figures used in these conversions up to date. Data for current exchange rates is kept at . Data for historical exchange rates are kept at . Data for the inflation rate is at (see *Template:Inflation#Developer documentation* for details). Feel free to update these if you are able.
