A1 - Units of measurement

Table of contents:

With the units of measurement we measure different things or aspects. We will come across them every time we want to quantify something. For example, with measures such as meters and kilometers we can measure length. With measures such as gram, kilogram and ton we can measure weight.

For us the most important measurements are those of the following items:

Length measurements (With units such as the following: centimeter, meter, kilometer).

Measures of weight (With units such as gram, kilogram)

Measures of time (with units such as second, minute, hour)

Monetary measures (with units of the type cent, peso, cent, dollar)

Area measures (With units of the type square centimeter, square meter)

Volume measures (With units of type cubic centimeter, cubic meter, liter)

To solve this problem, we'll follow these steps:

  • Step 1: Identify the given amount in milliliters which is 3850ml 3850 \, \text{ml} .
  • Step 2: Use the conversion factor 1dm3=1000ml 1 \, \text{dm}^3 = 1000 \, \text{ml} .
  • Step 3: Divide the milliliters by 1000 to convert to cubic decimeters.

Now, let's work through each step:
Step 1: We have 3850ml 3850 \, \text{ml} .
Step 2: We need to convert this volume to cubic decimeters using the conversion factor where 1000ml=1dm3 1000 \, \text{ml} = 1 \, \text{dm}^3 .
Step 3: Perform the conversion by dividing the milliliters by the conversion factor:

3850ml1000ml/dm3=3.85dm3 \frac{3850 \, \text{ml}}{1000 \, \text{ml/dm}^3} = 3.85 \, \text{dm}^3

Therefore, the solution to the problem is 3.85dm3 3.85 \, \text{dm}^3 .

Answer:

3.85dm3 3.85dm^3

Exercise #4

Convert 6112cm3 61\frac{1}{2}cm^3 into cubic decimeter.

Step-by-Step Solution

Let's solve the problem through a series of steps for ease of understanding:

  • Step 1: Identify the volume in cubic centimeters.
    The given volume is 6112cm3 61\frac{1}{2} \, \text{cm}^3 .
  • Step 2: Convert the mixed number to an improper fraction.
    The mixed number 6112 61\frac{1}{2} can be rewritten as 61+12 61 + \frac{1}{2} which equals 1222+12=1232 \frac{122}{2} + \frac{1}{2} = \frac{123}{2} . This is equivalent to 61.5 cubic centimeters.
  • Step 3: Convert cubic centimeters to cubic decimeters.
    Using the fact that 1dm3=1000cm3 1 \, \text{dm}^3 = 1000 \, \text{cm}^3 , we divide the given volume by 1000 to convert from cubic centimeters to cubic decimeters.
    1232÷1000=1232000=61.51000 \frac{123}{2} \div 1000 = \frac{123}{2000} = \frac{61.5}{1000}

Frequently Asked Questions

How do you convert meters to centimeters?

+
To convert meters to centimeters, multiply by 100. For example, 20 meters = 20 × 100 = 2,000 centimeters. Remember that 1 meter equals 100 centimeters.

What are the most important units of measurement to learn?

+
The six essential measurement types are length (meters, centimeters), weight (grams, kilograms), time (seconds, minutes, hours), money (dollars, cents), area (square meters), and volume (liters, cubic centimeters).

How do you solve currency conversion word problems?

+
First, identify the exchange rate given in the problem. Then multiply the amount by the conversion rate. For example, if 1 dollar = 17.50 pesos, then 10 dollars = 10 × 17.50 = 175 pesos.

What's the difference between area and volume measurements?

+
Area measures two-dimensional surfaces (like squares or rectangles) using units squared (cm², m²). Volume measures three-dimensional space using units cubed (cm³, m³) or liters.

How many cubic centimeters are in one liter?

+
There are 1,000 cubic centimeters (cm³) in one liter. To convert cm³ to liters, divide by 1,000. For example, 10,000 cm³ = 10,000 ÷ 1,000 = 10 liters.

Why is it important to write units in measurement problems?

+
Writing units prevents calculation errors and shows exactly what quantity you're measuring. Always include the unit (like 100m or 100cm) rather than just the number (100) to avoid confusion.

How do you calculate the area of a rectangle in different units?

+
Multiply length × width using the same units, then convert if needed. For a 2m × 3m rectangle: Area = 6 m². To convert to cm²: 6 m² × 10,000 = 60,000 cm².

What are the basic time unit conversions?

+
Key time conversions include: 1 minute = 60 seconds, 1 hour = 60 minutes, 1 day = 24 hours. Always multiply by the conversion factor when going from larger to smaller units.
