Question

Convert the following to the equivalent measures indicated. \(0.7 \mathrm{~L}=\) ______ \(\mathrm{mL}\)

Short answer

700 mL

Step-by-step solution

Understand the Relationship

To convert liters (L) to milliliters (mL), you need to know the conversion factor: 1 liter equals 1000 milliliters. This is because 'milli' means a thousandth, so there are 1000 milliliters in a liter.

Set Up the Conversion

You start with the measurement you have, 0.7 L. You will multiply this by the conversion factor to find the equivalent in milliliters. Here, the conversion factor is 1000 mL per 1 L.

Perform the Calculation

Multiply 0.7 by 1000 to convert the value to milliliters. Use the conversion equation: \[ 0.7 ext{ L} \times 1000 \frac{ ext{mL}}{ ext{L}} = 700 ext{ mL} \].

Check Your Answer

Ensure that the units in your conversion cancel out correctly, with liters on the denominator and numerator cancelling each other out, leaving milliliters as the remaining unit. This confirms that the conversion is appropriately done.

Key concepts

Unit Conversion

Unit conversion is a key concept in science, math, and daily life. It allows you to express a particular measurement in different units. This process is especially handy when you need to understand or communicate values across different systems.

• Conversion Factors: These are the ratios used to convert one unit of measurement into another. For example, when converting from liters to milliliters, the conversion factor is 1000. This means 1 liter equals 1000 milliliters.
• Equations and Ratios: Set up your conversion using an equation. Arrange the conversion factor so units cancel out properly, keeping in mind the relationship between the numerator and the denominator. This ensures you end up with the correct units and the right value.

Unit conversions are often straightforward, like converting 0.7 liters to milliliters, which involves multiplying 0.7 by 1000 to get 700 milliliters. Understanding these principles helps when measuring ingredients, planning projects, or in various academic disciplines.

Measurement Systems

Measurement systems organize and standardize units as we use them in various aspects of life. Two key systems are the Metric System and the Imperial System.

• The Metric System: The metric system is the most widely used measurement system worldwide. It is based on powers of ten, making it simple and consistent. Units include meters for length, liters for volume, and grams for weight.
• The Imperial System: Used primarily in the United States, it includes units such as inches, feet, and miles for length, and gallons and pints for volume.

Understanding these systems and their conversions is essential in fields like engineering, science, and even cooking. Each system has specific units and conversion factors. Recognizing how these units relate within and across systems is a valuable skill that helps with calculations and improves precision in measurements.

Mathematics Education

Mathematics education plays a crucial role in developing numeracy and problem-solving skills. These are essential in both academic settings and daily life. Unit conversion is a fundamental topic in this educational journey.

• Learning Foundations: From a young age, students start learning about numbers and measurements. As they progress, they tackle more complex topics like unit conversion. Understanding relationships between different units, like liters to milliliters, boosts comprehension and application in math and science.
• Real-World Applications: Learning to convert units accurately prepares students for real-world tasks, from scientific research to budgeting and cooking. It's a practical life skill that extends beyond classroom learning.

By focusing on these foundational skills, educational programs aim to build significant competence in mathematics. This helps students navigate detailed tasks with confidence, setting them up for successful problem-solving both in further education and in everyday challenges.
