Measurement( Week 12 Evaluation)

1. 7 × (1 gal 2 qt) = gal qt.

2. Metric system weight unit conversion.

3 metric tons = grams

4000 grams = kilograms

2000 kilograms = metric tons

1 kilogram = 1000 grams

1 metric ton = 1000 kilograms

3. Metric system volume unit conversion.

5 liters = milliliters

3000 milliliters = liters

4000000 milliliters = cubic meters

1 liter = 1000 milliliters

1 cubic meter = 1000 liters

4. Time unit conversion.

4 microseconds = nanoseconds

5 milliseconds = microseconds

4000000 nanoseconds = milliseconds

5000000000 nanoseconds = seconds

1 microsecond = 1000 nanoseconds

1 millisecond = 1000 microseconds

1 second = 1000 milliseconds

5. Time unit conversion.

3 minutes = seconds

2 days = minutes

4 days = hours

518400 seconds = days

1814400 seconds = weeks

1 minute = 60 seconds

1 hour = 60 minutes

1 day = 24 hours

1 week = 7 days

6. 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 lb. 10 oz.?

7. In the computer industry, the data units are bit, byte, kilobyte, megabyte, gigabyte, terabyte, ... and so on.

1 byte	=	8 bits
1 kilobyte	=	1024 bytes
1 megabyte	=	1024 kilobytes
1 gigabyte	=	1024 megabytes
1 terabyte	=	1024 gigabytes

How many kilobytes are equivalent to 24,576 bits?

8. Metric system length unit conversion.

1 kilometer = meters

1 hectometer = decimeters

1 decameter = centimeters

1 meter = kilometers

1 decimeter = millimeters

1 centimeter = hectometers

1 millimeter = meters

1 kilometer = 10 hectometer	1 hectometer = 10 decameter	1 decameter = 10 meter
1 meter = 10 decimeter	1 decimeter = 10 centimeter	1 centimeter = 10 millimeter

9. Inches, feet, yards, and miles are used in the U.S. customary length system.

1 foot (ft.) = 12 inches (in.)

1 yard (yd.) = 3 feet

1 mile (mi.) = 1760 yards

How many feet are in 9 miles?

10. (2 ft 6 in) ÷ 2 = ft in.
