Basic Measurements

A1–A2 · BeginnerEnglish Basics

Learn common English words for length, height, weight, volume and temperature.

What you'll learn

  • US and metric length units
  • Tall vs. high, long vs. wide vs. deep
  • US and metric weight and volume units
  • "By" for dimensions, "per"/"a" for rates

Length / distance

US customary

inch / inches — in

foot / feet — ft

yard / yards — yd

mile / miles — mi

Metric

millimeter — mm

centimeter — cm

meter — m

kilometer — km

This lesson is primarily about language, not conversion values.

Height, width, length, depth

The table is 6 feet long.

The door is 3 feet wide.

The wall is 8 feet high.

The pool is 6 feet deep.

For people and many upright things, we use tall: "He is six feet tall." Tall and high aren't always interchangeable.

Weight

US customary

ounce — oz

pound — lb

Metric

gram — g

kilogram — kg

It weighs 10 pounds.

The bag is 5 kilograms.

In full words we mark the plural (10 pounds); unit symbols generally don't take an -s (5 kg, not 5 kgs).

Volume

US customary

fluid ounce — fl oz

cup — cup

pint — pt

quart — qt

gallon — gal

Metric

milliliter — mL

liter — L

These are US customary volume units. US and British imperial units with the same names can have different sizes.

Temperature

°F — degrees Fahrenheit

°C — degrees Celsius

Examples: 70°F, 20°C

This lesson doesn't teach exact conversion between °F and °C — approximate conversions aren't treated as exact here.

"By" for dimensions

8 feet by 10 feet

12 inches by 18 inches

"By" can state two dimensions together.

"Per" / "a"

60 miles per hour / 60 miles an hour

$5 per pound / $5 a pound

Real life

Measurements appear in home improvement, shopping, travel, cooking and weather reports.
