Currency Exchange
Daily Norges Bank exchange rates for 38 currencies against the Norwegian krone (NOK) — EUR, USD, GBP, SEK, DKK and 33 more — with free charts, a converter, history back to about 1980, and MCP access for AI assistants.
USD / NOK — Exchange Rate
Norges Bank daily reference rates, not retail quotes. The curve uses a five-observation average (three for one week); tooltips show actual published observations. Long histories are sampled; gaps over seven days remain breaks. The vertical scale follows the observed range, not zero.

How much of a US dollar price should each country pay? One number per country, from World Bank GNI per capita (PPP) — a Bangladeshi household has roughly one-eighth the buying power of an American one, and today pays the same price for the same ebook. The recommended factor is a multiplier on the USD price: 1.00 is full price, and it never goes above that. The raw measurement does, for countries wealthier per capita than the United States.
Annual World Bank observations: curves average up to five neighboring observations within each uninterrupted run; tooltips show the published values. Missing years remain gaps. This is country-level income, not an individual household budget.

Source: World Bank NY.GNP.PCAP.PP.CD — GNI per capita, PPP (current international $), published once a year. Factor is
min(1, max(0.35, (GNI ÷ US GNI)0.5)). The floor exists because card fees of $0.30 + 2.9% eat more than a tenth of a smaller charge. The same numbers are available at /api/buyingpower and over MCP as
get_buying_power and list_buying_power.

Service information
Norges Bank exchange rates, updated every business day
Every rate on this page is the official daily reference rate published by Norges Bank, the central bank of Norway, quoted against the Norwegian krone. Norges Bank publishes once per business day at about 16:00 CET and the service syncs shortly after, so a NOK exchange rate here is the same number the bank published — not an interbank quote, not a retail rate, and never interpolated for a weekend or a Norwegian public holiday. Cross-rates between any two currencies (EUR to USD, say) are derived through NOK.
The rate table, the charts and the converter are free and need no account. The same data is available to an AI assistant over MCP: see how to connect Currency Exchange to Claude or another MCP client.
Questions about Currency
What people use it for
Convert my foreign payment with a rate I can cite.
Yes. convert returns the converted amount with the Norges Bank reference rate and the publication date used. If the requested day has no observation, it can use an earlier rate within five days and states that fallback; your assistant should show it alongside the result.

Help me set local ebook prices people can afford.
Yes. get_buying_power returns a recommended multiplier derived from World Bank GNI per capita at purchasing-power parity, and your assistant can apply it to your USD list price before converting to local money. The recommended factor is capped at 1.0 and floored at 0.35; source-year and fallback fields show what it rests on. It is guidance for your decision, not a sales forecast.

Compare our euro costs with our dollar receipts.
