Frequently Asked Questions
Why use manual conversion instead of live rates?
Manual conversion is useful for historical analysis, budget planning with assumed rates, educational purposes, and situations where official rates differ from the rate you must use (e.g., corporate internal rates).
How often should I update rates?
Major currencies change 1 to 2 percent daily. Update weekly.
Can I batch convert multiple values?
This tool converts one value at a time. For batch conversion use a spreadsheet or command-line tool.
How do I convert currencies manually?
Enter the rate for your currency pair (for example 1 EUR = 1.08 USD), the amount, and the tool multiplies amount by rate to give the result. You can also convert in the other direction by inverting the rate. Manual conversion is useful for offline use, fixed-rate contracts, or when you want to apply your own bank or agreed rate instead of a live market rate.
