Convert mass and body weight between kilograms, grams, pounds, ounces, and stones for recipes, fitness, and shipping.
A weight converter switches effortlessly between the metric units of mass (kilograms, grams) and the imperial/US units (pounds, ounces, and the British stone). Whether you are following an American recipe from a Pakistani kitchen, measuring body weight for a medical form, shipping a parcel internationally, or comparing gym equipment specifications, accurate mass conversion matters. This tool runs entirely in your browser, supports decimals, and handles both very small amounts (grams for spices and jewelry) and large amounts (tonnes of construction material or freight).
Formula
Convert to kilograms (base), then kg to the target unit. 1 kg = 2.20462 lb. 1 lb = 16 oz. 1 stone = 14 lb = 6.35029 kg.You usually need to convert weight because something in front of you is in the wrong units — the new Fitbit shows your weight in pounds even though every doctor in Pakistan asks for kilos, a US-imported BabyBjorn carrier has a maximum load in pounds and your newborn was weighed in grams at AKUH, or a UK aunty asks 'how many stones is your husband now' and you have no frame of reference for stones. The kg-to-pound conversion is the workhorse: roughly multiply by 2.2 for a mental estimate, but the calculator gets you the actual figure your GP will write on the BMI line. The trickier conversion is grams for shipping — Pakistan Post, TCS, and most courier services price-bracket at 250g, 500g, and 1kg, so the difference between a 480g parcel and a 510g parcel is sometimes 200 rupees, which only matters when you suddenly realise you have been overpaying for months. Honest take: when buying gold or saffron, always weigh in grams or tola, never ounces — the troy ounce used in precious metals is 31.1g, not the 28.35g avoirdupois ounce, and shopkeepers know this confusion exists.

All supported units store a fixed conversion factor to kilograms (the SI base unit for mass). To convert, the tool multiplies your input by its source factor to reach kilograms, then divides by the target factor to produce the answer. This two-step 'base conversion' pattern works for any pair of linear units and avoids rounding error that creeps in when direct factors are chained for every pair. The pound-to-kilogram conversion factor 0.453592 is an internationally agreed definition, not a derived value — it has been exact since 1959.
