5. . Why use the metric system?
Volume measurements using the English system:
3 tsps = 1 Tbsp
16 Tbsp = 1 cup
2 cups = 1 pint
8 pints = 1 gallon
How many teaspoons are there in 1 gallon?
1 gallon = 8 pints = 16 cups
16 cups = 256 Tbsp = 768 tsp
There are 768 tsp in one gallon
Volume measurements using the metric system:
How many milliliters are in 1 liter?
1000 mL
kilo hecto Deca unit deci centi milli L . 1
