charge=* is used to specify the amount of the charge to use or access a facility. It is mostly used in combination with fee=yes or toll=yes. It can be used in combination with charge:conditional=* to state special exceptions to the default price.
Usage
Values for this key commonly have the following notation:
- charge = <amount> <currency code>[/<unit>][/<time unit>]
The amount should include any subunits (such as cents) if charged: for example, if the fee charged is $2.95, then tag this as 2.95 USD, and do not round the amount up to 3 USD. Subunits should be expressed in full (for example, 8.50 AUD instead of 8.5 AUD, or 1.500 KWD instead of 1.5 KWD for currencies divided into 1,000 subunits), and always use the decimal point as 
decimal separator.
If the amount charged is a whole number, omitting the subunits is allowed. So a fee of exactly €5 can be written as either 5 EUR or 5.00 EUR. However, some mappers prefer the latter because it clarifies that no rounding of the amount has occurred. For currency that has no subunits, such as Japanese Yen or Korean Won, no decimal part is used at all.
In Mauritania and Madagascar (the latter for the record), one khoum or one iraimbilanja is expressed as 0.2 MRU or 0.2 MGA respectively, to one decimal point. In Iran, one toman (an unofficial subunit in common use)[1] is expressed as 10 IRR.
Put a space character between the number of the amount and the currency code.
The currency code should be specified as in ISO 4217. Do not use currency signs (such as $, €, ¥, 円, or £) or local abbreviations, which are not identical to the ISO currency code (such as Kč).

In some cases the charge levied is per some unit. Some examples of these seen in use include person (charge per person), kWh (charge per kilowatt-hour of energy), 1.5 litre (charge per litre of some fluid such as water). The various vehicle categories defined in access=*, such as motorcar or hgv (Heavy goods vehicles) can also be used.
The optional time unit should not be abbreviated (use hour instead of h). In addition to discrete durations in units like minutes, hours, days, and weeks, other values such as night and day are used as well.
