About Weight Converter

The Weight Converter changes any value between milligrams, grams, kilograms, metric tons, ounces, pounds, and stone. Type a number, choose your From and To units, and the answer appears instantly alongside a plain-English sentence spelling out the conversion. A one-click swap button flips the two units, so you can turn a pounds-to-kilograms conversion into kilograms-to-pounds without retyping anything.

Most people arrive for one specific pair. Converting pounds to kilos, kilograms to pounds, or kilos to lbs takes a couple of taps: enter the weight, set the units, and read the exact figure — no rounding surprises, because every value is routed through grams using standard factors (1 lb = 453.59237 g, 1 oz = 28.349523125 g). The same holds for grams to ounces, kilograms to stone, or metric tons to pounds. Need a quick reference chart? Run a few round numbers like 1, 5, 10 and 25 through it and you have your own conversion table in seconds.

It works as a fast weight calculator on both desktop and phone, with a numeric keypad prompt for quick entry on mobile. It is completely free — no sign-up, no ads, and no limits on how many conversions you run. Every calculation happens entirely in your browser using precise, standard conversion factors, so the numbers you enter are never uploaded to a server.

Frequently asked questions

Is the weight converter free to use?
Yes. It is 100% free with no account, sign-up, or usage limits. You can convert as many weights as you like.
Which weight units can I convert between?
Milligrams (mg), grams (g), kilograms (kg), metric tons (t), ounces (oz), pounds (lb), and stone (st). You can convert between any two of these in either direction.
How do I convert pounds to kilograms?
Enter your value, set From to pounds (lb) and To to kilograms (kg), and the result appears instantly. One pound is about 0.4536 kg, so 150 lb comes out to roughly 68 kg. To go from lb to kg the other way around, use the swap button.
How do I convert kilograms to pounds (kilos to lbs)?
Set From to kilograms and To to pounds, type your value, and read the answer. One kilogram equals about 2.2046 pounds, so 70 kg is around 154.3 lb. The swap button flips it straight back to pounds-to-kg.
How many kilograms are in a pound?
One pound equals about 0.4536 kilograms, and one kilogram equals about 2.2046 pounds. Enter your value and the tool shows the exact figure instantly.
Is there a weight conversion chart or table I can use?
There is no fixed printed table, but you can build your own in seconds: run round numbers like 1, 5, 10 and 25 through the converter and note each result. Because it converts through grams with exact factors, your homemade chart is just as accurate as the tool.
Can I use this as a weight calculator?
Yes. It works as a quick weight converter calculator for any single conversion. Enter a value, pick the two units, and it does the math instantly, adding a plain-English sentence that spells out the result.
Does this convert power-to-weight ratio?
No. This tool converts a weight from one unit to another; power-to-weight ratio is a separate calculation (power divided by weight, such as horsepower per pound). You can use it to convert the weight part into your preferred unit first, then do the division yourself.
How do I reverse a conversion without retyping?
Use the one-click swap button. It flips your From and To units instantly, so a grams-to-ounces conversion becomes ounces-to-grams while your value stays in place.
How accurate are the conversions?
It uses exact standard factors: 1 ounce = 28.349523125 grams, 1 pound = 453.59237 grams, and 1 stone = 6350.29318 grams. Every value is converted through grams for precise results.
Can I use it on my phone?
Yes. The converter is lightweight and works in any modern mobile or desktop browser, with a numeric keypad prompt for fast entry on phones.
Is my data uploaded or stored anywhere?
No. All conversions happen locally in your browser using JavaScript. The numbers you enter never leave your device and are not sent to any server.
