Tips for Accurate Results
1) Use consistent rounding
For daily use, two decimal places are usually enough. For technical tasks, keep more decimal places.
2) Check your input unit first
Make sure your starting value is in kilograms, not grams or pounds. A unit mix-up creates large errors.
3) Keep context in mind
A tiny difference may not matter for personal weight tracking, but it can matter in lab work or commercial shipping.
