Fact Check: Does 1/8 Cup Equal 2 Tablespoons Across Us and Metric Systems?
By Sarah Jenkins
Q1: Is 1/8 cup simply half of a 1/4 cup?
Yes. Mathematically, 1/8 is exactly half of 1/4. If a recipe calls for 1/4 cup and you need to halve the yield, you require 1/8 cup, which translates directly to 2 level tablespoons or 1 fluid ounce.
Q2: Can I use two dessert spoons instead of measuring tablespoons?
No. Tableware flatware varies wildly by aesthetic design, holding anywhere from 7 mL to 12 mL of fluid. A culinary measuring tablespoon is a standardized unit holding precisely 14.79 mL in the US and 15 mL internationally. Flatware should never be substituted in baking.
Q3: How many milliliters are in 1/8 of a US cup?
An eighth of a standard US Customary cup contains 29.57 milliliters. In US nutritional labeling (legal cup), it rounds cleanly to 30 milliliters. In the metric system used across the UK and Canada, 1/8 of a metric cup is 31.25 milliliters.
Q4: How do I measure 1/8 cup of cold butter?
A standard US stick of butter equals 1/2 cup (8 tablespoons). One-quarter of that stick equals 1/8 cup, or 2 tablespoons. Cut the stick cleanly at the two-tablespoon mark printed on the wax paper wrapper, which weighs precisely 1 ounce (28.35 grams).
Q5: Does 1/8 cup of liquid weigh the same as 1/8 cup of flour?
No. One-eighth cup of water or vinegar weighs approximately 29.6 grams, whereas 1/8 cup of properly fluffed all-purpose flour weighs around 15.6 grams. Liquids possess significantly higher density than aerated dry powders.
