How to Measure Cups in a Water Bottle
1. Check the Label
Most water bottles show their size in ounces or liters. You can use the fact that 1 cup = 8 oz to figure out how many cups your bottle holds.
2. Divide by Ounces
Take the total ounces on your water bottle and then divide it by 8. This gives you the exact number of cups.
3. Use a Measuring Cup
If you have a measuring cup, you can pour water from your bottle into it to see the exact number of cups. This is helpful if you don’t know the bottle’s size.
Converting Between Cups, Liters, and Milliliters
Many water bottles show their size in liters or milliliters, so these conversions can help:
- 1 cup of water is about 237 milliliters (mL).
- 1 liter is about 4.23 cups.
- 500 mL (half a liter) is about 2 cups.
These are useful if your bottle is labeled in liters instead of ounces.
