Use conversion factors without losing track of the source unit.
Quick answer
Length and weight use fixed base-unit factors; temperature uses formulas.
Base Units
Length and weight use fixed base-unit factors; temperature uses formulas. In this context, base units matters because the output should match the task rather than simply produce a file or string. Review the result against the original input and keep an untouched copy when the workflow changes a file.
Rounding
Length and weight use fixed base-unit factors; temperature uses formulas. In this context, rounding matters because the output should match the task rather than simply produce a file or string. Review the result against the original input and keep an untouched copy when the workflow changes a file.
Precision
Length and weight use fixed base-unit factors; temperature uses formulas. In this context, precision matters because the output should match the task rather than simply produce a file or string. Review the result against the original input and keep an untouched copy when the workflow changes a file.
Practical example
Use the matching Get Tools Lab Unit Converter tool with a small, non-sensitive example first. Confirm the expected result before using a larger or important input.
Privacy and limitations
Processing behavior depends on the tool. Priority browser-local tools identify that behavior on the tool page. A local browser workflow reduces server upload exposure, but it does not remove the need to protect the source file, device and downloaded result.
