What is a fingerbreadth in length measurement?

A fingerbreadth is an informal unit based on the width of an adult finger, commonly used for rough measurements in various contexts such as tailoring, medical exams, and gardening.

What is a Roman actus and what was it used for?

The Roman actus is an ancient Roman unit of length equal to 120 Roman feet, used historically for land measurement and cadastral surveying.

Is the conversion between fingerbreadth and Roman actus exact?

No, due to the variable nature of the fingerbreadth unit and the ancient status of the Roman actus, conversions are approximate and best suited for rough translation or educational purposes.

Browser-based and easy to use without installation

Examples

10 Fingerbreadths converts to approximately 0.005369416 Roman actus
100 Fingerbreadths converts to approximately 0.05369416 Roman actus

Common Use Cases

Tailoring, woodworking, and casual measuring where approximate fingerbreadth units are used
Roman cadastral and agricultural land surveying documentation
Historical and archaeological research involving ancient Roman distance units
Educational scenarios teaching about ancient measurement systems

Tips & Best Practices

Use this tool when approximate human-based measurements need conversion to ancient Roman units
Keep in mind the fingerbreadth unit varies by individual and context, so treat conversions as approximate
Use the converted values primarily for understanding or educational purposes rather than precise engineering
Cross-check conversions against known historical data when used in academic research

Limitations

Fingerbreadth is a non-standard, informal measurement, so exact value accuracy cannot be guaranteed
Roman actus is an archaic unit rarely used outside historical contexts
Conversions are inherently approximate due to the variable nature of fingerbreadth
Not suitable for high-precision modern surveying or engineering tasks
