SI prefixes, also known as a metric prefixes, are names or associated symbols that precedes a unit of measure or its symbol to form decimal multiples or submultiples. SI prefixes are used to reduce the quantity of zeroes in numerical equivalencies.

Femto (f) 10-15 One Quadrillionth

Pico (p) 10-12 One Trillionth

Nano (n) 10-9 One Billionth

Micro (µ) 10-6 One Millionth (greek letter 'mu')

Milli (m) 10-3 One Thousandth

Centi (c) 0.01 One Hundredth

Deci (d) 0.1 One Tenth

one = initial value

deka (dk) = 10 Ten

hecto (h) = 100 Hundred

Kilo (k) 103 One Thousand

Mega (M) 106 One Million

Giga (G) 109 One Billion

Tera (T) 1012 One Trillion

Peta (P) 1015 One Quadrillion

How many times larger is a centigram than a decagram?

These are SI units using standard prefixes. The interpretation of common prefixes is as follows: kilo = 1000 hecto = 100 deca = 10 deci = 0.1 centi = 0.01 milli = 0.001 Therefore, 1 centigram is 0.01 grams and 1 decagram is 10 grams. A decagram is 1000 times larger than a centigram.


How much is 156 cm?

The same as 1.56 meters. The prefix "centi" means 1/100.The same as 1.56 meters. The prefix "centi" means 1/100.The same as 1.56 meters. The prefix "centi" means 1/100.The same as 1.56 meters. The prefix "centi" means 1/100.


How much is 1.5 ml in liters?

Remember K H D | d c m (kilo, hecto, deka, (liter, meter, gram), deci, centi, milli). Milliliters are three places to the right of liters. So you have to move the decimal place three times to the right. You will get 1.5 L = 1,500 mL.


What are some common metric prefixes used in chemistry?

The prefixes go up or down in thousands. The common fractions of the base unit are; milli- thousandth, micro- millionth, and nano- billionth. the common multiples of the base unit are; kilo- thousand, mega- million, and giga, billion. centi/hect, and deci/deca aren't used.


What do the important prefixes of the metric system mean?

In the metric systems, unlike other systems, there is only one unit for each measurement; e.g the only unit for length is the metre. For lengths much longer, or shorter, lengths we use prefixes to indicate the fraction or multiple of the metre. For short lengths the fractions are thousandths, millionths, billionths; for which the prefixes are milli-, micro-, and nano-. For longer lengths, the multiples are thousands, millions, and billions; for which the prefixes are kilo-, mega-, and giga-. The prefixes indicate the fraction,or the multiple of the base unit.
