Nanogram Discussion

[deoxy99]

We've only made like a nanogram. Not enough to power a house for a day!

There is no such thing as a nanogram. You are supposed to put "a billionth of a gram" because nanogram is not real.

Ummm... wrong. You may add the prefix nano- to any measurment, just like kilo.

Go here instead:

Go to this section:

"General use of prefix names and symbols

Twenty SI prefixes are available to combine with units of measure. For example, the prefix kilo- denotes a multiple of one thousand, so 1 kilometre equals 1000 metres, 1 kilogram equals 1000 grams, 1 kilowatt equals 1000 watts, and so on. Each SI prefix name has an associated symbol which can be used in combination with the symbols for units of measure. Thus, the "kilo-" symbol, k, can be used to produce km, kg, and kW, (kilometre, kilogram, and kilowatt). SI prefixes are internationally recognized and also exist outside the SI (many of them long pre-date SI, going back to the original introduction of the metric system); prefixes may also be used in combination with non-SI units; for example: milligauss (mG), kilofoot (kft) and microinch (µin).
Prefixes may not be used in combination. This even applies for mass, for which the SI base unit (which is the kilogram, not the gram) already contains a prefix. So milligram (mg) is used instead of microkilogram (µkg), for example.
Prefixes corresponding to an exponent that is divisible by three are often recommended. Hence "100 m" rather than "1 hm" (hectometre) or "10 dam" (decametres). The "non-three" prefixes (hecto-, deca-, deci-, and centi-) are however more commonly used for everyday purposes than in science"

Umm... that doesn't help you. It tells anyone that, you can use the 20 SI prefixes on any base unit. Explain what part really helps your argument.

No it tells you that you can use a prefix on any measurement.

[atomic7732]

Ummm... If i recall, thats basically what I said.

If, you can use a prefix (SI prefixes) on any measurement (base unit).

And, nano is a prefix.

Then there is a nanogram.

Therfore:

prefix + base unit = nano + gram
