Some currencies (eg dollars) are used in a number of countries, so use the country symbol as well as the currency symbol (eg US$5, A$5, NZ$5, HK$5). If it’s clear which country’s currency you’re writing about, then just the currency symbol will do. For example, NZ$ wouldn’t be repeated throughout the New Zealand content.
Spell out ‘per’ in prices throughout the text, eg $5 per hour (not $5/hour).
When an amount of currency is specified, abbreviate the unit of currency (colloquialisms apart, eg bucks, greenbacks, quid).
B&Bs generally cost £20 to £40 per night.
If no amount is specified, spell out the unit of currency.
The best rates are given for US dollars and euros.
Use ‘to’, not a hyphen when giving a price range in text.
Prices range from ¥500 to ¥750.
The word ‘range’ indicates a span, so two figures must follow.
Prices start at US$30, not Prices range from US$30.
Repeat the currency symbol in price ranges in text only if the number and the currency symbol are closed up.
200B to 400B
Do not repeat the currency symbol or name when prices are separated by a solidus.
US$20/30
When mentioning cost in digital articles, they should be listed in the local currency, followed by the USD equivalent in brackets. If the US equivalent is over $20, round to the nearest dollar.
"An adult ticket to the aquarium costs £45 (US$57), while a child ticket is £25 (US$32)."
"Train rides up the mountain cost five lev (US$2.74)."
The first mention of a local currency in an article should be spelled out in its entirety. Subsequent instances can use just the currency name or symbol, as applicable.
"One-day admission to Disney Sea for adults is ¥7,900–9,400 Japanese yen (US$54-64). Teens cost ¥6,600–7,800 (US$45–53) and children are ¥4,700–5,600 (US$32–38)."
"You can expect to get a decent meal for around 15 Bulgarian lev (US$8.21)."
