2014年8月11日 · The Mega prefix (symbol M) means one million, so you could say the distance is 384 Megameters or 384 Mm. Substituting the metric prefix can make doing calculations easier in your head. Use the prefix that applies to your situation.

Mega is a unit prefix in metric systems of units denoting a factor of one million (10 6 or 1 000 000). It has the unit symbol M. It was confirmed for use in the International System of Units (SI) in 1960. Mega comes from Ancient Greek: μέγας, romanized: mégas, lit. 'great'. [1]

Table of metric prefixes for SI units.

Kilo, mega, giga, tera, peta, exa and zetta are among the binary prefixes used to denote the quantity of something, such as a byte or bit in computing and telecommunications. Sometimes called prefix multipliers, these prefixes are also used in electronics and physics.

This page deals with the prefixes of the units of the international system, the powers of 10 (Kilo, Mega, Giga, etc.). To convert numbers to scientific notation $ 1.23 \times 10^4 $ , dCode has a tool for that:

2018年5月18日 · Mega is the prefix for "one million", so for example a megawatt means one million watts. In scientific notation, you express numbers through powers of ten, so one million #=1000000 = 10^6#

The absolute exponential distance between 3 and -2 is 5, not 1. Done as an exponent, the absolute exponential distance between kilo- and centi- is 10 5 . In the problems to follow, the exponential form will be the one used.

Changing between metric prefixes, such as “kilo” or “mega,” is simply the same as multiplying or dividing by powers of 10. Following the above rules for multiplication and division, we see that we need only add to or subtract from the exponent on the 10! Can you verify the following examples?

2010年1月13日 · Three for forming multiples: mega, giga, and tera. Three for forming submultiples: micro, nano, and pico. Two prefixes for forming submultiples were added: femto and atto. This created an imbalanced situation, where there were more prefixes for small quantities. Two prefixes for forming multiples were added: peta and exa. Four prefixes were added.

The first three (Tera, Giga, Mega) are abbreviated with 1 upper case letter (T, G and M, respectively). Then, the rest are 1 lower case letter (k, h, d, c, m, n, p), except deca (da) and micro (μ). So, here goes, the mnemonic I created for the 12 prefixes in sequence: Tera – T he; Giga – G reat; Mega – M an; kilo – k ing; hecto – h ...
