# CharrgRate ## API Docs - Root > Currency Conversion [Convert a specified source amount](https://docs.charrgrate.leogcltd.com/convert-a-specified-source-amount-44184554e0.md): Use when the amount being converted is known in the source currency. The response contains the source currency in from and one result per destination in to[]. Each to[].mid is the converted destination amount for the requested source amount. A unit rate can be calculated as to[].mid / amount. Pricing is managed by LEOGC; from, to, and amount are required; inverse and decimal_places are optional customer query parameters. Use returned values according to your agreed payment workflow. This read-only operation does not execute a payment or create a guaranteed, stored quote. All numeric examples are illustrative and independent of the other operation examples. The string values in terms and privacy are placeholders for the service metadata. - Root > Currency Conversion [Calculate the source equivalent of a target amount](https://docs.charrgrate.leogcltd.com/calculate-the-source-equivalent-of-a-target-amount-44184555e0.md): Use when a target amount is known in the destination currency. The response contains the target currency in to and one source-currency equivalent in each from[] entry. Each from[].mid is the source amount corresponding to the requested target amount. The source-per-target unit value is from[].mid / amount; the target-per-source value is amount / from[].mid. Pricing is managed by LEOGC; from, to, and amount are required; inverse and decimal_places are optional customer query parameters. Use returned values according to your agreed payment workflow.
