To determine how many 8-ounce cups make up a liter, we need to do a conversion calculation. Since 1 liter is equal to approximately 33.8 fluid ounces, we divide 33.8 by 8. This gives us approximately 4.225. Therefore, there are around 4.225 cups of 8 ounces in a liter. Keep in mind that this is an approximate value, as cups can vary slightly in size.
