Study Notes
Metric Units Overview
- Meter (m) is the fundamental unit of length in the SI system.
- Liter (L) is the primary unit for measuring liquid volume in the SI system.
- Gram (g) serves as the standard unit for measuring mass in the SI system.
Smaller and Larger Units
- Millimeter (mm) equals 0.001 meter; 1,000 millimeters make up 1 meter.
- Centimeter (cm) equals 0.01 meter; 100 centimeters make up 1 meter.
- Milligram (mg) equals 0.001 gram; 1,000 milligrams equal 1 gram.
- Kilogram (kg) equals 1,000 grams; approximately 2.2 pounds.
- Milliliter (mL) equals 0.001 liter; 1,000 milliliters fill 1 liter.
Units for Length and Distance
- Kilometer (km) measures long distances; 1 kilometer is 1,000 meters.
- Hectometer (hm) equals 100 meters, less commonly used.
- Decameter (dm) equals 10 meters, also infrequently encountered.
- Nanometer (nm) equals 1 billionth of a meter, used for microscopic measurements.
- Micrometer (μm) equals 1 millionth of a meter; the diameter of a human hair is about 50 micrometers.
Measurement Categories in SI System
- Mass reflects the amount of matter in an object, measured in grams (g).
- Liquid volume, indicating how much space a liquid occupies, is measured in liters (L).
- Length represents the shortest distance between two points, measured in meters (m).
- Time is quantified using seconds (s).
Metric System Characteristics
- The metric system uses a base-ten approach, relying on the number 1.
- It is designed for accuracy in scientific measurements, forming the basis of the SI system.
- Watt (W) is the unit for measuring power or electric current strength, typically indicated on light bulbs.
Supplementary Time Measurements
- Millisecond (ms) is a measure of time, equal to one thousandth of a second, and 100 times greater than a nanosecond.
