1. 9 × (1 lb 1 oz) = lb oz.

2. There are ounces, pounds and tons used in the U.S. customary weight system.

1 pound (lb.) = 16 ounces (oz.)

1 ton (t.) = 2000 pounds

How many ounces are in 11 pounds?

3. American customary system weight unit conversion.

2 tons = ounces

3 tons = pounds

4000 pounds = tons

1 pound = 16 ounces

1 ton = 2000 pounds

4. Time unit conversion.

5 microseconds = nanoseconds

3 seconds = microseconds

4 seconds = milliseconds

5000000000 nanoseconds = seconds

1 microsecond = 1000 nanoseconds

1 millisecond = 1000 microseconds

1 second = 1000 milliseconds

5. Time unit conversion.

5 quarters = months

2 years = quarters

4 centuries = years

2 centuries = decades

6000 months = centuries

20000 quarters = millenniums

1 quarter = 3 months

1 year = 4 quarters

1 decade = 10 years

1 century = 10 decades

1 millennium = 10 centuries
