This page follows one figure on the USGS facts about water page: 59.843 pounds for one cubic foot at the boiling line. The 100-degree line, 61.998, stays on pounds per cubic foot at 100 F. Multiply cubic feet by 59.843. The reverse divides pounds by 59.843.
Cubic feet of water, or pounds. Not a gallon weight.

What Is Pounds per Cubic Foot at 212 F Using?
The printed boiling line is 59.843 pounds for each cubic foot. The result is a weight of water at that line. It does not say how large a tank is, how much chemical to feed, or whether a sample passed a lab. Write the temperature next to the factor so the next visit does not swap in 62.416.
One factor, both directions
The water-facts page prints 62.416 pounds for each cubic foot at 32 degrees Fahrenheit, 61.998 pounds for each cubic foot at 100 degrees Fahrenheit, and 59.843 pounds for each cubic foot at 212 degrees Fahrenheit. This page uses 59.843 so a cubic foot at the boiling line round-trips through pounds. It does not build the weight from gallons, and it does not use the gram-per-cubic-centimeter figure of 0.95865 that the same page prints at 100 degrees Celsius.
One pound divided by 59.843 is about 0.016710 cubic feet. Rounded to four decimals, that display reads 0.0167. The engine divided by 59.843. It did not divide by 62.416, and it did not divide by 61.998.
Worked examples
Each row uses 59.843. One cubic foot is 59.843 pounds. Two cubic feet are 119.686 pounds. The reverse of 59.843 pounds is 1 cubic foot. One pound is 0.0167 cubic feet at four decimals.
| Case | Pounds | Cubic feet |
|---|---|---|
| 1 cubic foot | 59.843 | 1 |
| 2 cubic feet | 119.686 | 2 |
| 59.843 pounds | 59.843 | 1 |
| 1 pound | 1 | 0.0167 |
212 F is not 100 F
The 100-degree line, 61.998, stays on pounds per cubic foot at 100 F. The 32-degree line, 62.416, stays on pounds per cubic foot at 32 F. Florida's 62.4 line stays on the cubic feet to pounds converter. This page has no 62.416, no 61.998, and no 8.33.
What to write on the job ticket
Write five lines before the number leaves this page. A later visit should not have to guess which temperature line was used.
- The entered value, and whether it was cubic feet or pounds.
- The factor, 59.843, named as the USGS line at 212 F.
- Both results, pounds and cubic feet.
- Which tank, tag, or sheet the volume came from.
- A note that 62.416, 61.998, and 8.33 were not applied.
What stays off this weight
A cold tank and a boiling line can both be called a cubic foot. This page does not ask which temperature produced the number beyond the factor it uses. A dose in milligrams per liter is a different tool, and this converter does not replace it.
A water treatment dealer who saves the 59.843 note will not swap in 61.998 and call the result the boiling line. This conversion does not size a softener and does not say a sample passed a county rule. A private-well lab sheet is still the well water testing guide.
The reverse uses the same factor. Divide the pound number by 59.843 to get cubic feet. One pound displays as 0.0167 cubic feet at four decimals. Two cubic feet display as 119.686 pounds. Those rows are arithmetic on 59.843. They are not a recommended tank weight and they are not a chemical dose.
Frequently Asked Questions
What does this boiling-line converter change?
It converts cubic feet of water and pounds using 59.843, the figure USGS prints for one cubic foot at 212 degrees Fahrenheit. It does not use 62.416, 61.998, or 8.33.
Why not use 62.416 or 61.998?
Those are the 32-degree and 100-degree lines on the same USGS page. Each temperature has its own page. This page uses 59.843 only.
Is 8.33 pounds per gallon used?
No. The same USGS list prints 8.33 pounds per gallon. That figure is not a factor on this page. A gallon weight is a different tool.
Does the result dose a chemical?
No. The result is a weight of water at the 212-degree line. It does not read a tank, a dose, or a flow.
What is 1 divided by 59.843?
One pound divided by 59.843 is about 0.01671 cubic feet. Rounded to four decimals, the display reads 0.0167. The engine divided by 59.843.
