If you want to learn more about unit conversion, this is the quiz for you.

Unit Conversion Questions and Answers

1.

Which of the following conversions is INCORRECT?
- A.
  
  1 meter = 100 centimeters
- B.
  
  1 kilogram = 1000 grams
- C.
  
  1 liter = 1000 milliliters
- D.
  
  1 kilometer = 100 meters
Correct Answer
D. 1 kilometer = 100 meters

Explanation
The correct conversion is 1 kilometer = 1000 meters. The prefix "kilo" in the metric system denotes a factor of 1000. The other options are correct: a meter is indeed composed of 100 centimeters, a kilogram contains 1000 grams, and a liter consists of 1000 milliliters.

How many centimeters are in 1.23×10−⁶ kilometers?
- A.
  
  0.123 cm
- B.
  
  0.1234 cm
- C.
  
  0.12 cm
- D.
  
  0.13 cm
Correct Answer
A. 0.123 cm

Explanation
To convert kilometers to centimeters, you need to use the conversion factors: 1 kilometer = 1,000 meters and 1 meter = 100 centimeters.

So, to find out how many centimeters are in 1.23 x 10^-6 kilometers: 1.23 x 10^-6 km x 1,000 meters/km x 100 centimeters/meter = 1.23 x 10^-6 x 100,000 = 0.123 centimeters.

So, the answer is 0.123 centimeters.

Approximately how many hours are there in 34.5 years?
- A.
  
  302,000 hrs
- B.
  
  302,220 hrs
- C.
  
  0.00394 hrs
- D.
  
  0.00393835 hrs
Correct Answer
B. 302,220 hrs

Explanation
To calculate the number of hours in 34.5 years, you can use the following calculation:

Number of hours in a year × Number of years

There are typically 365 days in a year, and each day has 24 hours. So, in a non-leap year:

365 days/year × 24 hours/day = 8,760 hours/year

Now, you can multiply this by the number of years:

8,760 hours/year × 34.5 years = 302,220 hours

So, there are approximately 302,220 hours in 34.5 years.

How many inches are there in 355 millimeters?
- A.
  
  13.97 inches
- B.
  
  14.90 inches
- C.
  
  140.0 inches
- D.
  
  139.0 inches
Correct Answer
A. 13.97 inches

Explanation
To convert millimeters to inches, you use the conversion factor: 1 inch = 25.4 millimeters.

So, to find out how many inches are in 355 millimeters: 355 mm / 25.4 mm/inch ≈ 13.9764 inches

Rounded to two decimal places, 355 millimeters is approximately equal to 13.98 inches. This conversion is helpful for understanding lengths and dimensions in different units, like when comparing metric and imperial measurements in construction, engineering, and everyday tasks where precision in measurement is important.

How many inches are there in 10 meters?
- A.
  
  278
- B.
  
  393
- C.
  
  403
- D.
  
  782
Correct Answer
B. 393

Explanation
To convert meters to inches, you use the conversion factor: 1 meter = 39.37 inches.

So, to find out how many inches are in 10 meters: 10 meters x 39.37 inches/meter = 393.7 inches

Rounding to the nearest whole number, the answer is 393 inches. This means that 10 meters is equivalent to 393 inches. Understanding this conversion is useful for various measurements in everyday life and scientific contexts, ensuring accurate conversions between metric and imperial units.

How many feet is 2.1 meters equal to?
- A.
  
  4 feet
- B.
  
  5 feet
- C.
  
  6.89
- D.
  
  10 feet
Correct Answer
C. 6.89

Explanation
To convert meters to feet, you use the conversion factor: 1 meter = 3.281 feet.

So, to find out how many feet are in 2.1 meters: 2.1 meters x 3.281 feet/meter ≈ 6.89 feet

Therefore, 2.1 meters is approximately equal to 6.89 feet. This conversion is useful for understanding lengths and dimensions in different units, such as when comparing metric (meters) and imperial (feet) measurements in everyday tasks, construction, and sports where distances and heights are commonly measured in feet. Understanding conversion factors helps ensure accurate communication and measurement across different unit systems.

What is 14 mm equivalent to in meters?
- A.
  
  0.014m
- B.
  
  0.0014m
- C.
  
  0.14m
- D.
  
  1400
Correct Answer
A. 0.014m

Explanation
To convert millimeters to meters, you use the conversion factor: 1 meter = 1,000 millimeters.

So, to find out how many meters are in 14 millimeters: 14 mm / 1,000 mm/meter = 0.014 meters

This means that 14 millimeters is equal to 0.014 meters. Understanding this conversion is important for accurately measuring small lengths and distances, ensuring precise measurements in various scientific and practical contexts.

  0.0057 L
- D.
  
  5700 L
Correct Answer
A. 0.057 L

Explanation
To convert milliliters (mL) to liters (L), you use the conversion factor: 1 liter = 1,000 milliliters.

So, to find out how many liters are in 57 milliliters: 57 mL / 1,000 mL/L = 0.057 liters

This means that 57 milliliters is equal to 0.057 liters. Understanding this conversion is important for accurately measuring volumes, whether in scientific experiments, cooking, or other practical applications. Knowing how to convert between different units of measurement ensures precision and consistency in various tasks and calculations.
