Math measurement chart: customary and metric units One upright page on Letter or A4 in ten tall rows. Customary units of length, weight and capacity on the left, from 1 foot = 12 inches to 1 gallon = 4 quarts; metric units of length, mass and capacity on the right, from 1 centimeter = 10 millimeters to 1 kiloliter = 1,000 liters.

How it works

This math measurement chart sets customary units on the left and metric units on the right: 12 inches in a foot, 16 ounces in a pound, 1,000 meters in a kilometer. Every line was checked against the tables NIST publishes.

Print the chart

Press Print the chart. It prints on one page, on Letter or A4. Fuller charts of the customary units, the metric prefixes, the abbreviations and the units of time are sheets of their own.

Customary and metric side by side

One sheet sets the two systems against each other: 1 inch = 2.54 centimeters, 1 kilogram = 2.205 pounds, 1 gallon = 3.785 liters. Three of its values are exact, and the sheet says which.

What the metric prefixes mean

The prefix says how many of the unit: kilo is 1,000, hecto 100, deka 10, deci a tenth, centi a hundredth and milli a thousandth. So a centimeter is a hundredth of a meter.

  • For a measurement chart for math practice, the fill-in sheets leave the numbers out. The filled charts are the answer sheets.

Questions and answers

How many cups are in a gallon?

16. A gallon is 4 quarts, a quart is 2 pints and a pint is 2 cups, so 4 × 2 × 2 = 16 cups. That is 128 fluid ounces.

How many feet are in a mile?

5,280 feet. A mile is also 1,760 yards, because a yard is 3 feet, and 63,360 inches.

What is the difference between customary and metric units?

U.S. customary units are inches, feet, pounds, cups and gallons, each with its own number to remember. Metric units are meters, grams and liters, which go up and down in tens.

How many centimeters are in an inch?

Exactly 2.54. So a foot is exactly 30.48 centimeters and a yard is exactly 0.9144 meter. A meter is about 39.37 inches, a little longer than a yard.

How many ounces are in a pound?

16 ounces, and a ton is 2,000 pounds. Fluid ounces are another unit: they measure capacity, 8 to a cup and 16 to a pint.

Units and what each equals 5

  • Customary units chart: length, weight and capacity Nine customary units, each with everything it equals: a yard is 3 feet and 36 inches, a quart is 2 pints, 4 cups and 32 fluid ounces, a gallon is 4 quarts, 8 pints and 16 cups.
  • Math measurement chart: customary and metric units One upright page on Letter or A4 in ten tall rows. Customary units of length, weight and capacity on the left, from 1 foot = 12 inches to 1 gallon = 4 quarts; metric units of length, mass and capacity on the right, from 1 centimeter = 10 millimeters to 1 kiloliter = 1,000 liters.
  • Measurement abbreviations chart: in, ft, lb, cm, kg, mL Ten customary units and ten metric units, each with the short form written after a number: 12 in, 3 ft, 5 lb, 30 cm, 2 kg, 250 mL. The liter is written with a capital L.
  • Metric prefixes chart: kilo to milli Seven tall rows from kilo, 1,000, down to milli, 0.001, each with its unit of length, mass and capacity: kilometer, kilogram, kiloliter. Each row is ten times the row under it.
  • Units of time chart: seconds to centuries Nine lines in tall rows, from 1 minute = 60 seconds to 1 century = 100 years, with the 365 days of a year and the 366 of a leap year.

Customary and metric side by side 1

  • Customary and metric units side by side: inches to centimeters, pounds to grams Ten customary units with what each is in metric units, and ten metric units with what each is in customary units: 1 inch = 2.54 centimeters, 1 kilogram = 2.205 pounds, 1 gallon = 3.785 liters. The values are the ones NIST prints.

Charts to fill in 2

  • Customary units chart to fill in: 11 boxes A name line and eleven lines such as 1 foot = and inches with an empty box between them for the number. The customary units chart is the answer sheet.
  • Metric units chart to fill in: 9 boxes A name line and nine lines such as 1 kilometer = and meters with an empty box between them. Every answer is 10, 100 or 1,000; the first chart has them all.

How this list was compiled: Every unit, symbol and value was checked against NIST Handbook 44, Appendix C, General Tables of Units of Measurement, 2026 edition, read October 16, 2026. The units of time are from the Wikipedia articles Unit of time and Gregorian calendar, read the same day. Licence: own work
