Measurement Units in the Metric System

Milli (m) represents 0.001 or one-thousandth.
Gram is the basic unit for mass in the metric system.
Density is defined as mass divided by volume (p = m/V).

Significant Figures

Nonzero digits are always significant.
Zeros between significant figures are also significant.
Zeros at the end of a number and to the right of the decimal point are significant.
Leading zeros (before the first nonzero digit) are not significant.

Measurement Precision

Precision indicates the scale or measurement device used for measurement.

Base Units in English and Metric Systems

Slug is the base unit for mass in the English system.
Gallon is the basic base English unit for measuring volume.
Weight measures the pull of gravity on an object.
Volume indicates how much space an object occupies.
Gram is the metric unit for weight.
Liter is the basic metric unit for volume.

Meniscus in Liquid Measurement

The meniscus is the curve at the surface of a liquid in response to its container, and volume is measured at the center of this curve.

Mass Measurement

Mass measures how much matter exists in an object.

Problem-Solving Methods

Factor-label method involves listing units with numbers when solving problems.
Significant figures and accurate representations are critical in scientific notation.

Graduated Cylinder Usage

A graduated cylinder is a tool used by chemists to measure volume, resembling a rain gauge with markings (graduations) for measurement.
