📘 Interpreting Your Bill
1 CCF = 100 Cubic Feet
1 CCF ≈ 748 Gallons
1 CCF ≈ 748 Gallons
If your bill says you used 5 CCF, you used 500 cubic feet of water.
Since each cubic foot contains about 7.48 gallons, 500 cubic feet equals roughly 3,740 gallons.
🧠 Why CCF?
Utility companies use CCF because measuring in gallons would result in huge numbers on the meter.
Example: A family might use 8,000 gallons a month.
In CCF, that's just ~10.7 units. It is much easier to read and bill.
✍️ Worked Example
Bill Reading: 12 CCF
Step 1: Convert to Cubic Feet -> 12 × 100 = 1,200 ft³.
Step 2: Convert to Gallons -> 1,200 × 7.48 = 8,976 Gallons.
📊 Real-World Applications
- Leak Detection: A usage of 1 CCF overnight while everyone is asleep indicates a major leak (748 gallons!).
- Pool Filling: Estimating cost to fill a pool (often 15,000+ gallons) using municipal water rates.
- Gardening: Calculating irrigation volume.
✅ Key Takeaways
- "C" is the Roman numeral for 100.
- CCF is the standard billing unit for municipal water.
- 1 CCF is roughly equal to 15 standard bathtubs of water (50 gallons each).
