# How Much Butter is in 1/3 Cup? How Many Tablespoons?

5.26 tablespoons make up a third of a cup of butter. The 8 ounces and 16 tablespoons in the typical American cup quantity. Since one-third of a whole is equal to one-third of it, or.33, then.33 of 16 tablespoons equals 5.26 tablespoons. Since an imperial cup similarly holds 16 imperial tablespoons, the same calculation holds true for the British imperial system.

## US Customary and British Imperial Systems of Measurement Differ

The U.S. customary cup holds 8 U.S. fluid ounces as opposed to the imperial cup’s 10 imperial ounces, which is significant when it comes to recipes. Because fluid ounce measurements differ between the U.S. customary and imperial systems, tablespoon measurements will also vary. The tablespoon, ounce, and cup measurements in millilitres (mL) are compared between American customary and imperial system units below:

14.79 mL is equal to 1 US tablespoon.

14.21 mL is equal to 1 tablespoon in the UK.

1 fluid ounce (US) equals 29.573 mL

28.413 mL is equal to 1 fluid ounce in the United Kingdom.

235.59 mL make up one U.S. cup.

284.13 mL make up 1 U.K. cup.

5.26 U.S. tablespoons, or one-third of a cup, equals 77.795 mL of butter. However, 5.26 imperial tablespoons, or a third of an imperial cup, of butter, equals 74.74 millilitres. Even though the measurement differences appear to be slight, they might occasionally be enough to destroy a dish.

## Does it use the Imperial or US systems?

The amounts that are called for in certain recipes that you see online frequently lack any indication of whether they are in U.S. customary or imperial system units. Searching for cup or gill units might help you determine whether a recipe is in U.S. customary or imperial systems.

The gill is equally uncommon in recipes using U.S. customary units as it is in recipes using the imperial system of measurement. British home cooks like weighing their recipe portions over scooping them out. Therefore, measurements in recipes from U.K.-based recipe writers will probably be given in dry weight units or metric system weight units.

## Measurement cup

Even so, there are some recipes that may specify the 250 mL metric system cup. Since there are 16.67 metric tablespoons in a metric cup, 5.5 metric tablespoons of butter make up one-third of a cup.

## Conversion of Measurement Systems

Knowing how to convert values into various measurement units begins with understanding the distinctions between the various measurement systems. The task will be significantly simpler if your mobile device has a helpful app converter. For individuals who don’t want to deal with the conversion procedures, kitchen instruments like a digital kitchen scale and measuring scoops for the US customary, imperial, and metric systems will be useful.

## Fractions to Decimals Conversion

Some home cooks might feel uneasy around factions and would rather have the recipe portions given in decimals. Fractions are a division of a whole and a component of it.

The denominator is the lowest number in a fraction, and the numerator is the highest number. A dividing line known as a vinculum separates the top and bottom numbers in a fraction. Divide the numerator by the denominator of a fraction to obtain the equivalent fraction in decimal form. For instance, 1/3 or 13 equals.33.
