- •Both metric (kg) and imperial (lbs) units are shown at once, so you don't need a separate conversion
- •Useful for quickly filling in a placeholder weight value for a character, form, or test dataset
- •Every generation is independent and uniformly random across the full range

Frequently Asked Questions
What range of weights can this generate?
Between 45 kg and 140 kg (roughly 99 to 309 lbs), covering a broad adult range.
Is the pounds conversion accurate?
Yes, it's calculated directly from the kilogram value using the standard conversion factor, rounded to the nearest pound.
Is this weighted toward average weights?
No, every value in the range is equally likely - it's a uniform random distribution across the full range.
Is my data sent to a server?
No. The weight is generated and converted entirely in your browser.
Can I use this for a specific demographic range?
This tool uses one broad general-purpose range. For a custom range, use the Random Number Generator instead.
