The standard length of a Revenue chain is:

Question

Accepted Answer

The standard length of a Revenue chain is 33 Feet. Here's why:

*   **Option 2: 33 Feet (Correct)** The Revenue chain, primarily used for land measurement in cadastral surveys, is indeed 33 feet long. This specific length is crucial because it's directly related to the unit of measurement called a 'Karam' or 'Gattha', which is a fundamental unit in land measurement systems in many regions. The Revenue chain is designed to be easily divisible into these smaller units, making calculations and area determination straightforward.

Now, let's examine why the other options are incorrect:

*   **Option 1: 66 Feet (Incorrect)** A chain of 66 feet is the length of a Gunter's chain, also known as a surveyor's chain. While also used in land surveying, it's distinct from the Revenue chain. The Gunter's chain is specifically designed to be 1/80th of a mile and is divided into 100 links, each 0.66 feet long.

*   **Option 3: 30 Feet (Incorrect)** A length of 30 feet does not correspond to any standard or commonly used surveying chain.

*   **Option 4: 50 Feet (Incorrect)** A 50-foot chain is not a standard type of chain used in revenue or land surveying. While tapes of 50 feet are common measuring tools, they are not referred to as "chains" in the traditional surveying context.
