This library provides a simple framework to convert units of measurement for the script https://greasyfork.org/en/scripts/419825. It supports various unit types (e.g., length, weight, volume, temperature) and handles conversions with single or compound values.

"150 pounds" → Outputs: "68.03 kg"
"10x20 inches" → Outputs: "25.40 x 50.80 cm"
"5^3" → Outputs: "125 power"
Regex Matching for Units
const UnitType = "150 pounds".match(Units)[3].toLowerCase(); // Extracts the unit type
Value Extraction
const Units = new RegExp(
/^[ \t\xA0]*(-?\d+(?:[., ]\d+)?)(?:[ \t\xA0]*x[ \t\xA0]*(-?\d+(?:[., ]\d+)?))?[ \t\xA0]*

[ \t\xA0]*(?:\(\w+\)[ \t\xA0]*)?$/i
);
const UnitValue = "150 pounds".match(Units)[1].replaceAll(',', '.'); // Extracts numeric value
const SecondUnitValue = "150 pounds".match(Units)[2]?.replaceAll(',', '.') || 0; // Extracts second value if present
Value Conversion
const convertValue = (value, unitType) => {
const { factor, convert } = window.UConv[unitType] || {};
return convert ? convert(value) : value * factor; // Converts value using factor or custom function
};
New Unit Detection
const NewUnit = window.UConv[UnitType]?.unit || UnitType; // Detects target unit
Final Conversion Output
const ConvertedUnit = `${convertValue(parseFloat(UnitValue), UnitType).toFixed(2)}${SecondUnitValue != 0 ? ` x ${convertValue(parseFloat(
SecondUnitValue), UnitType).toFixed(2)}` : ''}`; // Formats output
Special Cases
const ConvertedUnit = "5^3".match(/\^(\d+\.?\d*)/)
? (NewUnit = 'power', Math.pow(parseFloat(UnitValue), parseFloat("5^3".match(/\^(\d+\.?\d*)/)[1])))
: ConvertedUnit; // Handles powers
Display Conversion
ShowConvertion('Units', NewUnit, ConvertedUnit); // Displays result
To add new units, modify the addConversion function in the UConv library:
addConversion(['unit1', 'unit2'], 'targetUnit', conversionFactor, optionalConvertFunction);
Example:
addConversion(['pound', 'lb'], 'kg', 0.453592); // Adds "pound" conversion to kilograms
