### The metric system is based upon what number?

• A.

5

• B.

3

• C.

10

• D.

25

C. 10
Explanation
The metric system is based upon the number 10. This means that it uses a decimal system, where each unit is a multiple or fraction of 10. This makes conversions between different units of measurement much easier, as you simply need to move the decimal point. For example, there are 100 centimeters in a meter, and 1000 meters in a kilometer. The use of base 10 makes the metric system more intuitive and consistent compared to other systems that use different conversion factors.

### "Kilo" means...

• A.

1000x

• B.

100x

• C.

10x

• D.

5x

A. 1000x
Explanation
"Kilo" is a prefix derived from the Greek word "chilioi," meaning "thousand." In the metric system, it is used to represent a factor of 1000. Therefore, when "kilo" is used as a prefix, it multiplies the value by 1000.

### 500kL = ____________hL

5000, 5,000, 5 thousand, 5 x 1000, 5000L
Explanation
The given question is asking for the equivalent value of 500kL in hL. The answer options provided, 5000, 5,000, 5 thousand, 5 x 1000, and 5000L, all represent the same value of 5000 liters. Therefore, the correct answer is 5000, 5,000, 5 thousand, 5 x 1000, 5000L.

Rate this question:

• 8.

### 500km = ____________hm

5000, 5,000, 5 thousand, 5 x 1000, 5000m
Explanation
The correct answer is 5000, 5,000, 5 thousand, 5 x 1000, 5000m. This is because 1 kilometer (km) is equal to 1000 meters (m). Therefore, to convert km to hm (hectometers), we need to multiply the given value by 10. In this case, 500 km multiplied by 10 equals 5000 hm.

Rate this question:

• 9.

### ________kL = 3400L

3.4, 3.40, 3.4kL
Explanation
The given equation states that 1 kiloliter (kL) is equal to 3400 liters. Therefore, the numbers 3.4, 3.40, and 3.4kL all represent the same volume of liquid, which is 3400 liters. The first two numbers are in liter units, while the last one is in kiloliter units.

### 5mL = _________L

0.005, 0.005L, .005
Explanation
The given question asks for the equivalent value of 5mL in liters. The correct answer is 0.005L, 0.005, or .005. This is because 1 liter is equal to 1000 milliliters. Therefore, to convert milliliters to liters, we divide the value by 1000. In this case, dividing 5mL by 1000 gives us 0.005L, 0.005, or .005.

### 1,500 cg  = _____________150 kg

• A.

True

• B.

False

B. False
Explanation
The given statement is false. 1,500 cg is equal to 15 kg, not 150 kg. This is because there are 100 centigrams (cg) in 1 gram (g), and 1,000 grams (g) in 1 kilogram (kg). Therefore, to convert 1,500 cg to kg, we divide by 100 to get 15 kg.

Rate this question:

• 17.

### 15 cm = 1.5 mm

• A.

True

• B.

False

B. False
Explanation
The statement "15 cm = 1.5 mm" is false. This is because 15 cm is equal to 150 mm, not 1.5 mm. Therefore, the correct answer is False.
