Great tips offering the best measurement skills to third graders

This resource provides fun, challenging 3rd grade measurement worksheets pdf with great tips offering the best measurement skills to third graders.

To enhance 3rd grader’s measurement skills, we’ll provide quick and easy conversion tables of:

  • Fahrenheit or Celsius in measuring different temperature scales
  • Customary or metric units for measuring length, weight, and volume.

Different countries use particular measurement scales and units when measuring temperature and length, weight, and volume.

Hence, kids need to perfect mastery of all the different measuring units and temperature scales conversions.

Quick Fahrenheit to Celsius conversion table

You’ll find a bright and quick Fahrenheit to Celsius conversion table below.

As earlier said, while some countries use the Fahrenheit scale, some instead use the Celsius scale to record temperatures. So learning how to convert between these scales will help you figure out the temperature of anything, body, or place, no matter which country you find yourself in.


Fahrenheit (0F)

Celsius (0C)

Boiling Water



Body temperature



Room temperature



Freezing point




NB: - An exciting general rule for converting Fahrenheit to Celsius is to take away 30 from the Fahrenheit value, then use half of the remaining value to convert to Celsius.

Customary and metric units of measure conversion table– length, weight, and volume







1 foot = 12 inches

10milliliters = 1 centimetres

1 yard = 3 feet

10 centimetres = 1 decimetres = 100 mm

1 yard = 36 inches

100 centimetres = 1 metre = 100 mm

1 mile = 1760 yards

1000 metres = 1 kilometre

1 mile = 5280 feet




1 pound = 16 ounces

1000 milligram = 1 gram

1 ton = 2000 pounds

10 centigrams = 100 milligrams


100 grams = 1 kilogram = 1000000mg


3 teaspoons = 1 tablespoon

10 mm = 1 centilitres

2 tablespoons = 1 fluid ounce

10 cl = 1 decilitre = 100 mm

8 fluid ounces = 1 cup

1 litre = 1000 mm

2 cups = 1 pint

100 centilitres = 1 litre = 1000mm

4 cups = 1 quart

1000 litres = 1 kilolitre

2 pints = 1 quart


4 quarts = 1 gallon


128 fluid ounces = 1 gallon


8 pints = 1 gallon


16 cups = 1 gallon
