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.
