# Chains Per Hour Calculator

The Chains per Hour Calculator is a useful tool for surveyors, engineers, or anyone working in land measurement. In older units of measurement, a “chain” is a unit equal to 66 feet. This calculator helps determine how many chains of distance are covered in a given period of time, providing a quick way to measure progress in tasks like surveying large areas or construction.

**Formula**

The formula to calculate chains per hour is:

Chains per Hour (CPH) = Feet Distance Covered (FD) / 66 / Time Taken (T).

Where:

**FD**is the distance covered in feet.**T**is the time taken in hours.**66**is the number of feet in one chain.

**How to Use**

- Enter the total distance covered in feet (FD).
- Input the time taken in hours (T).
- Click the “Calculate” button to get the number of chains covered per hour.

**Example**

Let’s say you cover 1320 feet in 2 hours. Using the formula:

CPH = 1320 / 66 / 2 = 10 chains per hour.

This means you are covering 10 chains per hour.

**FAQs**

**What is a chain in terms of measurement?**

A chain is an old unit of measurement that equals 66 feet or approximately 20.12 meters.**Why would I need to calculate chains per hour?**

It is useful for surveyors and land measurement tasks where speed and distance need to be tracked in terms of chains.**What fields use chains as a unit of measurement?**

Chains are often used in surveying, construction, and historical land division in some countries.**How do I convert chains to feet?**

To convert chains to feet, multiply the number of chains by 66. For example, 2 chains equal 132 feet.**How do I convert feet to chains?**

To convert feet to chains, divide the number of feet by 66. For example, 660 feet equals 10 chains.**Can I use this calculator for tasks other than surveying?**

Yes, the calculator can be useful for any task that involves covering distance over time, particularly where chains are used as the unit of measurement.**What if I measure time in minutes instead of hours?**

Convert the time into hours by dividing the number of minutes by 60. For example, 90 minutes is 1.5 hours.**What is the significance of using chains in modern measurement?**

Although not commonly used today, chains are still important in some regions and historical land documents, making it relevant in specific contexts like legal descriptions and surveying.**What is the origin of the term “chain”?**

The chain measurement originates from surveyor Edmund Gunter’s chain, a measuring device used in the 17th century, which is still referenced in surveying.**How accurate is the chains per hour calculation?**

The calculation is accurate as long as the distance and time inputs are measured correctly. It assumes consistent movement or progress over time.**Can this calculator be used in metric units?**

This calculator is specifically for chains and feet. You would need to convert metric measurements to feet before using it.**What if I only know the total time in minutes?**

Simply divide the total time in minutes by 60 to convert it into hours before entering it into the calculator.**Is this calculator useful for construction projects?**

Yes, especially in projects that use older units of measurement or for tracking progress in surveying and land development.**How many chains are in a mile?**

There are 80 chains in a mile, as 1 mile is equal to 5280 feet and 5280 / 66 = 80.**What if I need to calculate chains per minute instead of per hour?**

You can adjust the formula by dividing the time in minutes by 60 to convert it into hours, or you can calculate chains per minute by adjusting the time accordingly.**How do chains relate to other surveyor units?**

Chains are often used in conjunction with acres, with 10 square chains equaling one acre.**Can I use this calculator for hiking or long-distance walking?**

Yes, if you want to track your walking or hiking speed in terms of chains, this calculator can be used.**What if the time is less than 1 hour?**

If the time is less than 1 hour, simply enter the time as a decimal. For example, 30 minutes should be entered as 0.5 hours.**How can I improve my accuracy in measuring feet for this calculation?**

Use a reliable measuring tool like a measuring tape or surveyor’s wheel to ensure the distance in feet is accurately recorded.**Is there a standard for the speed in chains per hour?**

There is no specific standard, but in surveying, covering 10 to 20 chains per hour is considered a reasonable pace depending on terrain and conditions.

**Conclusion**

The Chains per Hour Calculator is a valuable tool for anyone working with land measurement or distance tracking. It provides a quick and accurate way to calculate the rate of progress in terms of chains, helping professionals in surveying, construction, and other fields track their work more effectively. With just a few inputs, you can determine how efficiently you are covering distance over time in chains per hour.
