Question

Using abbreviations and the rules of the metric system, express the following quantities correctly. Six tenths of a gram ______

Short answer

0.6 g

Step-by-step solution

Understand the Quantity

The given quantity is six tenths of a gram. In fractional form, this is represented as \( \frac{6}{10} \) grams.

Convert Fraction to Decimal

Convert the fractional quantity \( \frac{6}{10} \) to a decimal. This is simply 0.6 grams.

Use Metric Abbreviation

In the metric system, grams are abbreviated as 'g'. Thus, 0.6 grams is written as 0.6 g.

Verify Metric System Rules

According to metric conventions, decimal numbers should be expressed using a decimal point and correct unit abbreviation without any additional symbols or letters. Thus, 0.6 g follows these rules correctly.

Key concepts

abbreviations

Abbreviations are quite common in the metric system, simplifying complex units into easily recognizable short forms. In the metric system, units like meter, liter, and gram are abbreviated to m, L, and g respectively. This system ensures that anyone, regardless of their background, can quickly understand the measurements involved.
When dealing with smaller or larger quantities, prefixes are added to these abbreviations to indicate scale. For example:

• Kilogram (kg) represents 1,000 grams.
• Milligram (mg) signifies one-thousandth of a gram.
• Centimeter (cm) is one-hundredth of a meter.

These abbreviations help in communicating measurements efficiently without redundancy, ensuring clarity and precision in scientific and everyday contexts.

decimal conversion

Decimal conversion is the process of transforming a fraction into a decimal format. This skill is valuable in the metric system because it provides a quick and exact representation of measurements. Let's use the example from the exercise to illustrate this process.
Start with the fractional form of six tenths: \( \frac{6}{10} \). To convert this fraction to a decimal, you divide 6 by 10, resulting in 0.6. Thus, six tenths is written as 0.6 in decimal form.
This conversion is essential in the metric system because it aligns with the preference for decimal-based notation, providing a universally understandable and consistent format for conveying measurements.

metric conventions

Metric conventions encompass a set of rules and standards used globally to ensure the uniformity and clarity of measurements. One of the core principles is the use of decimalization, meaning all measurements should be expressed in terms of decimals rather than fractions.
Another important rule is the consistent use of standardized abbreviations that are recognized world-wide. Proper use of these abbreviations, such as using \( \text{g} \) for gram, ensures that anyone can understand the quantities being referred to, without confusion.
Furthermore, metric conventions dictate that numbers should be accompanied by a concise and correctly formatted unit abbreviation. No superfluous marks such as extra commas or symbols should appear. Thus, writing 0.6 g adheres strictly to metric conventions, making sure communication is both clear and accurate.
