In the metric system, there are three basic units to measure length, volume, and weight (mass). You have the meter (m) for length, liter (l) for volume, and gram (g) for weight. Each of these units is then broken down into smaller or bigger units using metric prefixes.

• Giga – G (1,000,000,000)
• Mega – M (1,000,000)
• Kilo – k (1,000)
• Hecto – h (100)
• Deka/deca – da (10)
• Deci – d (1/10)
• Centi – c (1/100)
• Milli – m (1/1000)
• Micro – μ (1/1,000,000)
• Nano – n (1/1,000,000,000)

The prefixes have the same meaning for each of the measurement units. For example, a kilogram is 1,000 grams and a kiloliter is 1,000 liters.

Now that you know the basic units and their prefixes, it is just a matter of putting the two together to create your different metric abbreviations. Starting with length, the meter (m) is your base unit. Then, you add the appropriate prefix for the corresponding metric measurement.

• Kilometer – km
• Square kilometer – km²
• Hectometer – hm
• Decameter (or dekameter) – dam
• Meter – m
• Decimeter – dm
• Cubic decimeter – dm³
• Centimeter – cm
• Cubic centimeter – cm³
• Millimeter – mm

With most basic metric abbreviations, you’ll include the prefix letter with the unit of measure. The noted exception is “deka” or “deca.” For example, the abbreviation for “decameter” is “dam.” This is because “dm” already stands for “decimeter.”

Just as the meter (m) is the base measurement for length in the metric system, the liter (l) is the base measurement for volume.

• Kiloliter – kl
• Hectoliter – hl
• Decaliter (or dekaliter) – dal
• Liter – l
• Deciliter – dl
• Centiliter – cl
• Milliliter – ml

For weight, the base measurement in the metric system is the gram (g). Add prefixes as you did above for meters and liters.

• Kilogram – kg
• Hectogram – hg
• Dekagram (or dekagram) – dag
• Gram – g
• Decigram – dg
• Centigram – cg
• Milligram – mg

While length, weight, and volume cover the basics, there are other units of measurement that are just as important. In America, you might be familiar with the Fahrenheit system for temperature, but the metric system uses Celsius and Kelvin.

The metric abbreviations for these are:

• Kelvin – K
• Celsius – C

If you’ve ever touched a computer, you’ve probably come across bits and bytes. You might not have known what that “b” or “B” stood for, but that is where learning computer storage abbreviations can help. Dive into the abbreviations from bits to exabytes.

• Bit – b
• Byte – B
• Kilobyte – KB (1,000 bytes)
• Megabyte – MB (1,000 KB)
• Gigabyte – GB (1,000 MB)
• Terabyte – TB (1,000 GB)
• Petabyte – PB (1,000 TB)
• Exabyte – EB (1,000 PB)

In the standard decimal system, each unit is equal to 1,000 of the previous units. However, in the traditional binary system, each unit is equal to 1,024 of the previous units. This is because 1,024 equals 2 to the 10th power (210).

One other area where you’ll come across metric system abbreviations is in the context of power, energy and electricity. These abbreviations include:

• Watt – W
• Kilowatt – kW
• Kilowatt-hour – kWh
• Gigawatt – GW
• Amp – A
• Milliamp – mA
• Milliamp-hour – mAh
• Volt – V
