Kilogram (kg): The SI base unit of mass. Used for body weight and groceries in most countries.
Use cases in Pakistan
In Pakistani markets, weight is quoted in a mix of traditional and metric units. Jewellers price gold per tola, karyana shops sell desi ghee and dry fruit by the kilogram or the traditional pao, and butchers weigh meat in kilograms. Parcels sent through TCS or Leopards are billed per kilogram, while imported supplements, gym diet charts and foreign recipes arrive in pounds and ounces. Converting between these units keeps both shopping and cooking accurate.
These are the tools people recommend to each other on WhatsApp — simple, free, no install — because they solve the small problems everyone hits: timing something, picking fairly, testing a device. Bookmark the ones you use; they age well.
Limitations
Metric and avoirdupois factors are exact by definition; the tola (11.6638 g) and maund (40 kg) use their standard Pakistani values. Displayed results are rounded for readability — for jewellery or laboratory work, weigh on a calibrated scale rather than converting. This tool does not adjust for purity (karat) when weighing gold.
Convenience tools are not certified instruments: fine for everyday purposes, but do not stake safety, money or legal outcomes on a browser utility. Know which category your use falls into.
