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

  1. Enter the total distance covered in feet (FD).
  2. Input the time taken in hours (T).
  3. 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

  1. 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.
  2. 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.
  3. What fields use chains as a unit of measurement?
    Chains are often used in surveying, construction, and historical land division in some countries.
  4. 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.
  5. 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.
  6. 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.
  7. 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.
  8. 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.
  9. 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.
  10. 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.
  11. 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.
  12. 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.
  13. 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.
  14. 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.
  15. 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.
  16. How do chains relate to other surveyor units?
    Chains are often used in conjunction with acres, with 10 square chains equaling one acre.
  17. 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.
  18. 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.
  19. 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.
  20. 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.
