Land, gold & fuel

Everyday & Conversion Calculators

Land area in marla and kanal, gold weight and value, electricity bills and load, solar payback and net metering, fuel cost, dates, age and CGPA.

Not everything here is tax. This group holds the everyday calculations that come up around Pakistani money and property: converting marla and kanal to square feet under both standards in use, valuing gold by tola or gram at the rate you enter, estimating an electricity bill under slab tariffs, and working out whether solar pays for itself.

The conversions state their assumptions — which marla standard, which calendar — because a quietly chosen convention is how a conversion ends up wrong by a fifth.
