The Square CM to Katha Conversion Chart helps you easily understand how land area measured in centimeters converts into Katha. Since Katha is an area unit and centimeters are a length unit, the conversion is calculated by first finding the total area in square centimeters using length and width, then converting it into Katha using a standard formula.

This chart is especially useful for land measurement, property dealing, construction planning, and real estate calculations, allowing users to quickly estimate land size without manual calculations.

The katha is a traditional unit of land area used across South Asia, especially in India, Nepal and Bangladesh. Because it is a customary unit, its exact size varies by region. Standard used on this page (Bihar/Jharkhand): 1 katha = 1,361 square feet = 1,264,500 square centimetres (126.45 square metres). Twenty katha make one bigha in the same system, which is why land records in Bihar and Jharkhand move naturally between the two units. Always confirm which local definition applies before using a conversion for legal or property documents, since other regions differ — West Bengal, for example, defines the katha as 720 square feet.

To convert square centimetres to katha, divide the area by 1,264,500. Worked examples make this concrete: a plot of 2,529,000 cm² equals 2,529,000 ÷ 1,264,500 = 2 katha exactly, while 632,250 cm² equals 632,250 ÷ 1,264,500 = 0.5 katha (half a katha). Going the other way, multiply katha by 1,264,500: 3 katha = 3 × 1,264,500 = 3,793,500 cm². Note that a centimetre is a unit of length, so you cannot convert a single length into katha — you must first multiply length by width to obtain an area, exactly as the formula section below shows.

You will reach for this converter whenever a small land measurement needs expressing in the units local people actually use: checking a plot’s size against a sale deed written in katha, estimating construction material for a katha-sized parcel, or comparing listings where one agent quotes square centimetres and another quotes katha. Enter the area in square centimetres, press Calculate, and the tool instantly returns the equivalent in katha, saving you the long division by 1,264,500. For quick mental estimates, remember that one katha is roughly 126 square metres, so a 1,000-square-metre plot is just under 8 katha (1,000 ÷ 126.45 ≈ 7.9).
