About

This tool acts as a semantic translator for physical quantities, scanning unstructured text for Imperial measurements and converting them into the Metric system. Unlike standard calculators that require isolated numbers, this engine parses full paragraphs, preserving the original context while appending or replacing values.

It recognizes complex patterns such as composite height (5'11"), weights (lbs, oz), distances (miles), and even US-style dates. This is particularly critical for internationalizing technical documentation, adjusting recipes for European kitchens, or translating literature where understanding the scale of 100 miles or 0°F is essential for the reader.

Formulas

The core conversions rely on the following standard coefficients defined by international agreement (ISO/NIST).

L_m = L_ft × 0.3048M_kg = M_lbs × 0.45359237T_C = (T_F − 32) × 0.5556

For fuel efficiency, the relationship is inverse, as MPG measures distance per volume, while L/100km measures volume per distance:

Fuel_L/100km = 235.215Fuel_MPG

Frequently Asked Questions

The tool detects patterns like 5'11" or 5ft 10in as a single entity. It sums the feet (multiplied by 30.48) and inches (multiplied by 2.54) to produce a total centimeter value, rather than converting them separately.

We use "word boundary" logic (\b) to minimize false positives. For example, it will convert "100 miles" but should ignore "Model-100" or "100miles" if formatted as a variable code. However, spacing matters.

Yes. The engine looks for common text fractions (1/2, 1/4, 3/4) and converts them to decimals (0.5, 0.25, 0.75) before applying the unit conversion formula.

By default, it converts US formats (MM/DD/YYYY) to the international standard (DD.MM.YYYY) or 24-hour time notation. This can be toggled off in the settings panel if you only want to convert physical units.
