How to use it

- Review the result and its assumptions before using it.
Common uses
- Checking a day-to-day calculation
- Comparing two options using the same units
- Getting a quick estimate before a decision
Compare products by cost per gram, item, litre or another matching unit instead of relying on package price alone.
Check the values, units, file type or output settings before you run the task. Keep the original input until you have checked the output, and confirm any external rules or platform-specific requirements that apply to your situation.
