UAE Unit, Area, Gold and Rate Converter Pack

Property ads quote square feet and the plan says square metres. Gold is quoted per ounce, per gram or per tola. Fuel economy is in l/100 km on one car and mpg on another. People convert these on a phone calculator and carry a rounding error or a wrong factor into an offer. This pack converts exactly and shows the factor it used, so you can check it.

On Convert, choose a category, type a value and pick from and to. Switch to A price per unit to turn AED 450 per sq ft into AED per square metre, or a gold rate per tola into per gram. Plot and price works out area from length and width and a total price. Gold gives the pure gold content and metal value from weight, karat and your own 24 K price. Fuel and mileage converts economy units and works out trip, monthly and yearly cost, or compares two vehicles. Factors shows every definition and prints a one-page cheat sheet.

What is inside:

• Convert, Plot and price, Gold, Fuel and mileage, Paper sizes, Factors and About tabs
• 55 units in six categories: area, length, weight, gold weight, volume and fuel economy
• Exact arithmetic with whole numbers and fractions; a rounded result is marked, and the exact fraction can be shown
• Plot size in sq ft, sq m, sq yd, acre, hectare, marla and kanal with a total price
• Gold: tola, troy ounce, pennyweight, grain, karat table, fineness to karat, metal value at the purity you choose
• Fuel: km/l, l/100 km, mpg (US and UK), trip cost, yearly cost and a two-vehicle comparison
• Paper sizes A0 to A10, B0 to B6, C4 to C6, DL and US sizes in mm, inches and pixels, plus a size finder
• Printable A4 cheat sheet for each category, JSON backup, example data

Who it is for: property buyers and agents, gold buyers and sellers, small fleets and drivers, designers and printers, and anyone who converts these units more than occasionally.

What it is not: It fetches no prices: you type the gold price and fuel price you use. Metal value leaves out making charges, margin and VAT. Marla and tola are not fixed everywhere, so they are settings with defaults of 272.25 sq ft and 11.6638038 g, and you should confirm them against your document or trade. Areas on a title deed or approved plan are the authority. It is not valuation, investment or legal advice.

How it differs: No existing catalogue product converts units or prices per unit. The property and finance tools use their own formulas and do not replace this one.

Tested: 226 scripted browser checks. Every ordered pair of units in all six categories, at seven values and in both quantity and price per unit modes (6,664 conversions), equalled an exact Fraction calculation built from the published definitions, with no mismatch. 486 conversions also agreed with the pint units library within one part in a billion. Display rounding was compared with an independent half-up routine, paper pixel sizes were checked against the ISO halving rule and known A4 and Letter values, and every cheat sheet printed to one A4 page. Tola and marla were checked against the definitions stated here, since pint has no standard value for them. It was tested in Chromium only. Firefox, Safari, a real phone and a real printer were not available for testing.
