Coding

const packer = require('@emealscom/packer')

const packerRequest = {
    description: "Broccoli",
    offerDescription: "Pack of 4 Broccoli",
    unitMeasure: "grams",
    unitQuantity: 480,
    packageUnitMeasure: "ounces",
    packageUnitQuantity: 12
};

console.log(packer.convert(packerRequest));

Result

➜  test node index
{ estimatedQuantity: 2, status: true }
