Correct invalid input before retrying; retry server-busy responses with bounded backoff. Returned files contain Base64 data, not persistent download URLs. Decode and inspect the output before treating conversion as successful. See the shared API guide for the complete status and timeout rules.\n\n### Browser-agent workflow\n\n1. Open the human page in a browser that supports WebMCP.\n2. Discover the interface exposed by that page; use its actual schema.\n3. Select files on the page first when the tool requires files.\n4. Call `run_current_tool` with valid input and settings.\n5. Inspect the returned result or error and the displayed output. Retrieve files from the displayed download links.\n\nCalls do not automatically copy or download results. Browser permissions still apply. Interface availability alone is not proof of successful execution.\n\n### Planning specification\n\nMass units, precision and clear mass/force distinction; link to kg-to-lb task.\n\nThis describes intended requirements. Use the implementation notes, interface schema and observed output to determine current support.\n\n### Complete machine-readable capability record\n\n```json\n{\n  \"id\": \"weight\",\n

([Markdown](https://happytails.ai/en/unit-converters/kg-to-lb.md))\n\n- [Length](https://happytails.ai/en/unit-converters/length/): Convert between meters, feet, inches, and other length units. ([Markdown](https://happytails.ai/en/unit-converters/length.md))\n\n- [Volume](https://happytails.ai/en/unit-converters/volume/): Convert between liters, milliliters, and US or Imperial volume units. ([Markdown](https://happytails.ai/en/unit-converters/volume.md))\n\n## How to use Weight\n\n1. Enter the values you want to calculate and choose the relevant units or settings.\n2. The result updates as you type. Adjust the available settings if needed.\n3. Review the result, then use Copy result or a download link when available.\n\n## What to expect\n\nConvert between kilograms, pounds, ounces, and other mass units. Enter a value and choose the source and destination units. Your result updates automatically. The calculation uses the selected units; displayed digits do not improve the accuracy of your original measurement.\n\n### Try a small example\n\n```\nChoose the units that match your measurement.\n```\n"
