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 12 pounds?

1 ton = 2000 pounds

4. Time unit conversion.

4 milliseconds = nanoseconds

5 seconds = microseconds

3000000 nanoseconds = milliseconds

4000000000 nanoseconds = seconds

1 microsecond = 1000 nanoseconds

1 millisecond = 1000 microseconds

1 second = 1000 milliseconds

5. Time unit conversion.

2 quarters = months

5 decades = quarters

4 decades = years

3 millenniums = decades

4800 months = centuries

60000 months = millenniums

1 quarter = 3 months

1 year = 4 quarters

1 decade = 10 years
