Frequently Asked Questions
How do I use the Unit Converter?
Pick a category tab (Length, Weight, Area, Volume, or Speed), enter a Value, then choose the units in the "Convert From" and "Convert To" dropdowns — the result updates instantly. Use the ⇄ swap button to reverse the conversion direction, and check the table below for all conversions of your entered value at once.
What unit categories does this converter support?
Length, weight, volume, area and speed. Each category has its own set of units selectable from the "Convert From" and "Convert To" dropdowns, and switching categories resets the unit list to that category's units.
What are Cent, Guntha and Ground, and how do they convert to square feet?
These are traditional Indian land area units. 1 Cent = 435.6 sq ft, 1 Guntha = 1,089 sq ft (1/40th of an acre), and 1 Ground (used in Tamil Nadu) = 2,400 sq ft. They're available alongside standard metric and imperial area units in the Area category.
How do I convert between metric and imperial units (e.g. km to miles, kg to lb)?
Select the category (Length or Weight), choose your source unit in "Convert From" and the target unit in "Convert To" — e.g. Kilometers to Miles or Kilograms to Pounds — then enter a value. The result updates instantly.
What does the swap (⇄) button do?
It instantly swaps the "Convert From" and "Convert To" units, so you can quickly reverse the direction of a conversion (e.g. switch from "Meters → Feet" to "Feet → Meters") without re-selecting both dropdowns.
What is the "All conversions from..." table for?
It shows your entered value converted into every other unit in the selected category at once — useful for quickly comparing a measurement across all available units without changing the "Convert To" dropdown repeatedly.
How accurate are the conversions?
Conversions use standard internationally accepted conversion factors (e.g. 1 inch = 2.54 cm exactly) and are displayed with several decimal places for precision. For land area units like Cent, Guntha and Ground, note that exact local definitions can vary slightly by region.
I need to convert my height/weight for a BMI calculation — can I use this tool?
Yes — convert your height (cm ↔ ft/in) and weight (kg ↔ lb) here, then use our BMI Calculator to find your Body Mass Index. For temperature conversions, see our Temperature Converter.
How many decimal places are shown in the results?
Results are rounded to 8 significant digits and formatted with Indian-style digit grouping (e.g. 12,34,567.89). For very large or very small numbers, this means trailing digits beyond the 8th significant figure are dropped rather than rounded to a fixed number of decimals.
Why might my Cent/Guntha/Ground conversion not match what my local registration office uses?
This tool uses commonly cited fixed values (1 Cent = 435.6 sq ft, 1 Guntha = 1,089 sq ft, 1 Ground = 2,400 sq ft), but some states and local land records define these units with slightly different rounding or historical survey conventions. For legal or registration purposes, always confirm the exact factor with your local sub-registrar or survey department.
