This is a simple/toy REST service in Node.js and Express using OpenAI API for converting and scaling weights and measures (it can be used for other purposes with a few changes).

You will need Node.js and npm

Get OpenAI API key. Copy .env.example to .env and add the API key there.

Do an npm install and run with npm start

It should be possible to test some weights and measures scaling with something like:

http://localhost:3000/scaleWeightsAndMeasures?quantity=20&fromUnit=ounces&toUnit=milliliters&scaleFactor=2

from a browser.

OR

curl 'http://localhost:3000/scaleWeightsAndMeasures?quantity=20&fromUnit=ounces&toUnit=milliliters&scaleFactor=2'

from commandline.

It will comeup with an answer like:

{"scaledValue":"Answer: 40 ounces is equal to 1136.5225 milliliters"}

Experiment with training data and question !
