The metric system is the measurement standard used in engineering and most scientific disciplines. The system is based on measurements for:

• Mass — grams
• Length — meters
• Volume — liters
• Temperature — degrees Celsius

Amounts are expressed in fractions or multiples of 10 and identified by adding a standard set of prefixes to the base unit. In measuring mass, some units for fractions of a gram are:

• Nanogram = 1,000,000,000th of a gram
• Microgram = 1,000,000th of a gram
• Milligram = 1,000th of a gram
• Centigram = 100th of a gram
• Decigram = 10th of a gram

Some units for multiples of a gram are:

• Decagram = 10 grams
• Hectogram = 100 grams
• Kilogram = 1,000 grams
• Megagram = 100,000 grams
• Gigagram = 1,000,000,000 grams
