Question

State the following metric-English equivalents: (a) \(1 \mathrm{~m}=? \mathrm{yd}\) (b) \(1 \mathrm{~kg}=? \mathrm{lb}\) (c) \(1 \mathrm{~L}=? \mathrm{qt}\) (d) \(1 \mathrm{~s}=? \sec\)

Short answer

(a) 1 m = 1.09361 yd, (b) 1 kg = 2.20462 lb, (c) 1 L = 1.05669 qt, (d) 1 s = 1 sec

Step-by-step solution

Conversion from Meters to Yards

To convert meters to yards, you use the conversion factor where 1 meter equals approximately 1.09361 yards. So, \[1 \mathrm{~m} = 1.09361 \mathrm{~yd}\].

Conversion from Kilograms to Pounds

To find out how many pounds are in a kilogram, use the conversion factor that 1 kilogram is equal to approximately 2.20462 pounds. Therefore, \[1 \mathrm{~kg} = 2.20462 \mathrm{~lb}\].

Conversion from Liters to Quarts

Convert liters to quarts by using the equivalent that 1 liter is approximately 1.05669 quarts. So, \[1 \mathrm{~L} = 1.05669 \mathrm{~qt}\].

Seconds to Seconds Conversion

A second is a unit of time and remains the same in either metric or English contexts. Thus, \[1 \mathrm{~s} = 1 \sec\]. Since the symbol is the same, they are directly equivalent.

Key concepts

Measurement Conversion

Measurement conversion is the process of converting a quantity expressed in one unit of measure to an equivalent value in another unit. This is an essential skill for anyone working in fields involving science, engineering, cooking, or any task where precise measurements are necessary. Understanding how to convert between different systems of measurement allows for effective communication and application of knowledge across different regions and industries.

• Conversions often use conversion factors, constants that provide the relationship between different units.
• In calculations, units can be multiplied, divided, and canceled just like numbers.

In our original exercise, we've converted metrics such as meters, kilograms, and liters into their English system counterparts. Mastery of measurement conversion helps ensure accuracy and understanding, regardless of the measuring system in use.

Units of Measure

Units of measure are standards used to quantify physical quantities like length, weight, volume, and time. Just like language, units provide a standardized way to communicate measurements clearly. Different systems of units allow for measurement in ways that suit different cultural and practical contexts.

• Basic units include meters for length, kilograms for weight, and liters for volume.
• Secondary units, like yards, pounds, and quarts, can be converted to and from these metric units.

Understanding units of measure is crucial because it allows for comparisons and calculations within and across various measurement systems. Recognizing the common units and their relationships is a foundational skill in many practical applications.

Metric System

The metric system is an internationally adopted system of measurement that is decimal-based, meaning it is built on powers of ten, which makes it easy to scale up or down. It provides a universal way of interpreting and calculating measurements.

• Key metric units include meters (m) for distance, kilograms (kg) for mass, and liters (L) for volume.
• This system is used globally across scientific and everyday measurements, providing consistency and ease of use.

Despite its widespread adoption, conversion to other systems like the English system might occasionally be necessary, especially in regions where both systems are used. This is where knowing metric-English equivalents becomes crucial for seamless integration of measurements across different contexts.

English System

The English system, also known as the imperial or customary system, is primarily used in the United States. It involves units like inches, pounds, and gallons, which are not based on a decimal system. This system is used often in everyday life and certain professional fields within countries that employ it regularly.

• English units can often seem confusing due to lack of easy conversion scales compared to the metric system.
• Common units in this system include yards (yd), pounds (lb), and quarts (qt).

To navigate different systems smoothly, such as during travel or international work, understanding English system units and their conversion factors with metric units is critical. This knowledge ensures accurate communication of measurements, allowing for effective planning and execution of projects across different measurement systems.
