Enter the average temperature (F) and the total number of days at that temperature into the Calculator. The calculator will evaluate the Ice Growth. 

Ice Growth Formula

IG = (32-AT) / 15 * D

Variables:

  • IG is the Ice Growth (inches of growth)
  • AT is the average temperature (F)
  • D is the total number of days at that temperature

To calculate Ice Growth, subtract the average temperature from 32, divide the result by 15, then multiply by the number of days at that temperature.

How to Calculate Ice Growth?

The following steps outline how to calculate the Ice Growth.


  1. First, determine the average temperature (F). 
  2. Next, determine the total number of days at that temperature. 
  3. Next, gather the formula from above = IG = (32-AT) / 15 * D.
  4. Finally, calculate the Ice Growth.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

average temperature (F) = 20

total number of days at that temperature = 5

FAQs

What factors can affect the accuracy of the Ice Growth calculation?

Several factors can affect the accuracy of the Ice Growth calculation, including variations in local climate conditions, the specific heat capacity of the ice, and environmental factors such as wind speed and water salinity.

Can this formula be used to predict ice growth in saltwater conditions?

While the basic principles might still apply, the presence of salt lowers the freezing point of water, requiring adjustments to the formula to accurately predict ice growth in saltwater conditions.

How does the thickness of ice affect its strength and stability?

The strength and stability of ice increase with its thickness. However, factors such as temperature fluctuations, snow cover, and the presence of impurities can affect its overall integrity.

Are there any safety considerations to keep in mind when estimating ice growth for recreational activities?

Yes, it’s crucial to consider safety when estimating ice growth for activities like ice fishing or skating. Always verify ice thickness physically in multiple locations, as ice growth can be uneven and influenced by underlying water currents or other factors.
