The most common cup measurement is the US customary cup, which is equal to approximately 240 milliliters (mL). However, it is crucial to note that there are also US legal cups (about 237 mL) and metric cups (exactly 250 mL).
Performing the Calculation
To convert 3 liters of water to US customary cups, we use the following conversion factor:
1 liter = approximately 4.22675 US customary cups
Therefore, 3 liters is equal to:
3 liters * 4.22675 cups/liter = approximately 12.68 US customary cups.
So, 3 liters of water is roughly equivalent to 12.68 US customary cups.
Accounting for Different Cup Sizes
As mentioned earlier, cup sizes can vary. If you’re using a US legal cup (237 mL), the conversion changes slightly:
1 liter = approximately 4.21667 US legal cups
3 liters * 4.21667 cups/liter = approximately 12.65 US legal cups.
If you’re using a metric cup (250 mL), the conversion is:
1 liter = 4 metric cups
3 liters * 4 cups/liter = 12 metric cups.
Therefore, it is essential to know the specific cup size you are using to ensure an accurate measurement. A standard measuring cup set will usually indicate the size.
