Frequently asked questions
Why include both pounds and stone?
Because different regions use different everyday weight conventions, especially for body weight and shipping contexts.
Can this help with fitness and body-weight tracking?
Yes. That is one of the most common use cases, especially when switching between kilogram- and pound-based plans.
Does rounding change the underlying conversion?
No. Rounding affects display only; the underlying factor-based conversion stays the same.
