Reference block: the method, a worked example and answers to common questions. It does not affect the calculation above.
How it is calculated
- The quotes come from the Bank of Russia’s official reference: every currency is quoted against the ruble, so any pair converts through it — first from the source currency into rubles, then from rubles into the target.
- Quotes keep their published nominal (the yen, for instance, is quoted per 100 units), and the whole cross rate — (source quote / nominal) / (target quote / nominal) — is carried as one exact fraction. The amount is scaled by it and rounded once, to the target currency’s decimals: two for the euro, zero for the yen.
- The displayed per-unit and inverse rates are rounded to four decimals for reading, but the amount is never multiplied by a displayed rate — on a large sum the rate’s rounding would cost real money.
- The amount field accepts expressions like “1 000 + 250” — handy for adding up banknotes. Currency names and decimal counts come from the reference data, and the quote date is shown under the result.
Worked example
Converting 1 000 dollars into euros, say, takes two steps: the thousand dollars becomes rubles at the central bank quote, and that ruble sum is divided by the euro quote. Both steps are one fraction, so the result does not depend on the order of roundings.
The inverse rate is derived from the same quotes rather than by dividing one by the direct rate — so the two directions agree, and a thousand dollars converted to euros and back returns to the original sum within a kopeck of rounding.
Frequently asked questions
Why does the rate differ from my bank or exchange office?
This is the official central bank rate — an accounting value with no spread. Banks and exchangers add their margin in both directions, so a cash rate is always worse. The calculator answers “what is this worth at the fair rate”.
How fresh are the quotes?
The reference date is shown under the result. Quotes refresh from the backend; offline, the built-in copy works — with the same date in sight, so a stale rate never poses as today’s.
Why are the yen and some others quoted “per 100”?
That is how the source publishes them: cheap units are quoted in batches so the rate is not a tiny fraction. The calculator stores the nominal and divides it in exact arithmetic — the result is unaffected, only the rate reads more comfortably.
Can I convert between two foreign currencies?
Yes, any pair in the book — dollars to euros, yuan to dirhams. The conversion always pivots through the ruble, because both quotes are against it; the single cross fraction prevents precision loss at the intermediate step.
Why does a yen result have no kopecks?
Each currency has its standard number of decimals: two for the ruble and euro, zero for the yen, three for a few others. The result is rounded to the target currency’s decimals — as a bank would when crediting the sum.
Does it include transfer fees?
No — only the rate arithmetic. Bank and payment-system fees depend on the transfer method; subtract them yourself. For trip budgeting, keep the calculation handy with the “Share” button.
