About US tablespoon (tbsp)

The US tablespoon (tbsp) is a unit of culinary volume equal to approximately 14.787 milliliters, defined as 3 US teaspoons or half a US fluid ounce. It is a fundamental cooking measurement in the United States for both liquid and dry ingredients. Butter is measured in tablespoons (1 stick = 8 tbsp), as are cooking oils, sauces, and spices. The US tablespoon differs from the Australian tablespoon (20 mL) and the imperial tablespoon (17.76 mL).

One tablespoon of olive oil is about 14 g. A standard butter portion is 1 tbsp (≈ 14 g).

About US liquid gallon (gal)

The US liquid gallon is a unit of volume equal to 4 quarts, 8 pints, or 128 US fluid ounces, approximately 3.785 liters. It is the primary large liquid volume unit in the United States, used for fuel pricing at the pump, milk and juice packaging, and paint. US fuel economy is measured in miles per gallon (MPG). The US gallon is about 17% smaller than the UK imperial gallon (4.546 L), causing significant differences in fuel economy comparisons.

A gallon jug of milk is 3.785 L. Petrol (gasoline) is priced per US gallon at every US fuel station.


US tablespoon – Frequently Asked Questions

One US tablespoon equals approximately 14.787 mL, typically rounded to 15 mL in culinary contexts. It equals 3 US teaspoons (3 × 4.929 mL = 14.787 mL).

The Australian tablespoon is 20 mL — about 35% larger than the US tablespoon (14.79 mL). When using Australian recipes: 1 Australian tbsp ≈ 1.35 US tbsp. This is a significant difference in baking.

There are 16 US tablespoons in one US cup (240 mL): 1 cup = 16 tbsp = 48 tsp = 8 fl oz.

US liquid gallon – Frequently Asked Questions

US fuel infrastructure — pumps, tax law, pipeline contracts, and consumer expectations — is built around the gallon. Federal and state fuel taxes are levied per gallon; EPA fuel economy standards use miles per gallon; and consumers benchmark prices against a gallon reference ("$3 a gallon"). Switching to liters would require reprogramming every pump, rewriting tax code, and re-educating 330 million people who compare prices by the gallon. Canada made the switch in the 1970s during a broader metrication push, but the US never had the political will for a comprehensive changeover.

The US gallon (3.785 L) is based on the Queen Anne wine gallon of 1707 (231 cubic inches). The UK imperial gallon (4.546 L) was defined in 1824 as the volume of 10 pounds of water. The two systems diverged after US independence.

To convert: L/100km = 235.2 ÷ MPG (US). A car achieving 30 MPG uses about 7.8 L/100km. UK MPG values are always higher than US MPG for the same car because the imperial gallon is larger.

Recommended daily water intake is about 2–3 liters (roughly 0.5–0.8 US gallons). The commonly cited "8 glasses a day" ≈ 64 fl oz ≈ 0.5 gallons ≈ 1.9 liters.

Most US passenger cars have fuel tanks of 10–20 gallons (38–76 liters). Compact cars are typically 10–13 gallons; mid-size cars 14–17 gallons; SUVs and trucks 18–36 gallons.
