Perplexity

Convert Weights via the MCP Server.

The `convert_weight` tool handles weight units, so you never have to manually calculate ratios. You input a measurement (like 5 lbs) and specify the target unit (oz), and it spits out the exact conversion instantly. It supports both metric and imperial systems, letting you cross-reference weights using standard units like kilograms and ounces without leaving your chat window.

Calculate Temperature Changes.

`convert_temperature` converts between Celsius, Fahrenheit, and Kelvin. Drop in a temperature reading—say, 32 degrees F—and the tool handles all three conversions for you. This is critical when dealing with scientific data or physical processes; it gives you precise readings whether you need to know the equivalent in K or C.

Handle Digital Storage Units.

The `convert_digital_storage` tool manages binary prefixes for storage sizes. Give it a value and tell it if it's in KB, and you get back the correct MB equivalent. It uses the standard 1024 base, which is essential when dealing with file system data or memory allocation reports.
