How to use (3 steps)
- Enter the amount, pick the “from” and “to” currencies, and choose whether you want a direct rate or a base-currency setup.
- Type your exchange rate exactly as quoted (for example, 1 USD = 148.23 JPY, or 1 USD = 0.92 EUR and 1 EUR = 160 JPY).
- Press Convert to see the converted amount, then use “Copy result URL” if you want to reopen the same scenario later.
Rates are entered manually and never fetched from an API. Always confirm important conversions with your bank or an official source.
Tips for Manual FX Conversion
- Quickly estimate travel budgets or reimbursement amounts without an FX API.
- If you only know rates versus a major currency (e.g. USD), use the base mode to bridge the gap.
- Decimals are supported, so you can enter precise quotes such as 1 USD = 148.23 JPY.

FAQ
How do I provide exchange rates?
This calculator does not call any external FX API. Enter either a direct rate such as “1 USD = 148 JPY” or use the base currency mode with two inputs: “1 FROM = ? BASE” and “1 BASE = ? TO”. The conversion uses your numbers as-is.
How can I verify the accuracy of the result?
The converted amount depends entirely on the rate you provide. Double-check important conversions with reliable sources, such as your bank or official market data, before making financial decisions.
What should I do first on this page?
Start with the minimum required inputs or the first action shown near the primary button. Keep optional settings at defaults for a baseline run, then change one setting at a time so you can explain what caused each output change.
Why does this page differ from another tool?
Different pages often use different defaults, units, rounding rules, or assumptions. Align those settings before comparing outputs. If differences remain, compare each intermediate step rather than only the final number.
How reliable are the displayed values?
Values are computed in the browser and rounded for display. They are good for planning and educational checks, but for regulated or high-stakes decisions you should validate assumptions with official guidance or professional review.
