Hello!

I know what I want to do but don’t know how to put the pieces together.

• Build a database
• Get data store and output
• Have users access it whenever they want. ex…

start mileage km | end mileage km | total km | convert mi | rate | total

5555 I 6666 | 1111 | 690.34 | $0.49 | $338.27

Would you do calculations with JavaScript before reaching the backend.or do the calculators with php at server level and store it. It some other language.
