Converters
Length, area, weight and other unit converters, including Indian land units.
Unit conversion comes up constantly, a recipe in a foreign measurement system, a spec sheet in inches when you think in centimetres, a road sign in kilometres, and converting by hand means remembering exact multipliers and hoping a decimal doesn't get misplaced along the way. This category covers standard metric and imperial converters (length, area, weight, volume, speed, time, temperature, energy, pressure, power, digital storage), all mathematically exact since they're fixed-ratio conversions, plus regional land-unit converters (bigha, biswa and similar) that are explicitly flagged as approximate and region-variable rather than presented with false precision. Every converter here routes through a common base unit internally, so converting between two unrelated units still comes out exact rather than compounding rounding errors across a chain of intermediate conversions. For a broader index that also includes file-format converters (PDF, image, audio, data), see the dedicated Converters hub, which combines both unit and file conversion in one place.
