What is bigger than mega?
mega = 106 giga = 109 tera = 1012 exa = 1015 peta = 1018
If K is short for hundred thousand what is the letter sign for million?
K is short for Kilo and also for thousand, M is short of Mega and also for million, G is short for Giga and for billion, followed by: * Tera -- trillion * Peta -- quadrillion * Exa -- quintillion * Zetta -- sextillion ...and from there, you're on your own ;}
What are metric prefixes from smallest to largest?
They are yocto (septillionth) zepto (sextillionth) atto (quintillionth) femto (quadrillionth) pico (trillionth) nano (billionth) micro (millionth) milli (thousandth) centi (hundredth) deci (tenth) UNIT deca (ten) hecto (hundred) kilo (thousand) mega (million) giga (billion) tera (trillion) peta (quadrillion) exa (quintillion) zetta (sextillion) yotta (septillion).
Si units in order largest to smallest?
Here's the full list of SI units I know of from largest to smallest: Yotta - Y - One septillion. (1,000,000,000,000,000,000,000,000) i.e. One yottameter / Zetta - Z - One sextillion. (1,000,000,000,000,000,000,000) i.e. One zettameter / Exa - E - One quintillion. (1,000,000,000,000,000,000,) i.e. One exameter / Peta - P - One quadrillion. (1,000,000,000,000,000) i.e. One petameter / Tera - T - One trillion. (1,000,000,000,000) i.e. One terameter / Giga - G - One billion. (1,000,000,000) i.e. One gigameter / Mega - M - One million. (1,000,000) i.e. One megameter / Kilo - k - One thousand. (1,000) i.e. One kilometer / Hecto - h - One hundred. (100) i.e. One hectometer / Deka - da - One ten. (10) i.e. One dekameter / Base - . - One (1) i.e. One meter / Deci - d - One tenth (.1) i.e. One decimeter / Centi - c - One hundredth (.01) i.e. One centimeter/ Milli - m - One thousandth (.001) i.e. One millimeter / Micro - μ - One millionth (.000001) i.e. One micrometer / Nano - n - One billionth (.000000001) i.e. One nanometer / Pico - p - One trillionth (.000000000001) i.e. One picometer / Femto - f - One quadrillionth (.000000000000001) i.e. One femtometer / Atto - a - One quintillionth (.000000000000000001) i.e. One attometer / Zepto - z - One sextillionth (.000000000000000000001) i.e. One zeptometer / Yocto - y - One septillionth (.000000000000000000000001) i.e. One yoctometer
How long is one quintillion seconds?
One quintillion seconds is equivalent to approximately 31.7 billion years. This is also the same as one exasecond (Es). This is calculated by dividing one quintillion (10^18) by the number of seconds in one whole year (31,536,000 seconds). To find out the number of years that are in one quintillion seconds, we first need to know how many seconds are in one year. Let's break down the calculation and explain each step of the process thoroughly. Step 1: Calculate the number of seconds in one minute. We know that there are 60 seconds in one whole minute. Step 2: Calculate the number of seconds in an hour. From Step 1, we can calculate this: 60 seconds/minute × 60 minutes/hour = 3,600 seconds. Step 3: Calculate the number of seconds in one day. Once again, from Step 2, we can calculate this: 3,600 seconds/hour × 24 hours/day = 86,400 seconds. Step 4: Calculate the number of seconds in one year, assuming a year has exactly 365 days: 86,400 seconds/day × 365 days/year = 31,536,000 seconds. Now, we can finally determine and calculate how many years are in a quintillion seconds! One quintillion is equal to 1,000,000,000,000,000,000 or 10^18. We can divide the total number of seconds that are in one quintillion by the total number of seconds that are in one year: Number of years = 10^18 seconds / 31,536,000 seconds per year After performing this calculation, we approximately get: Number of years ≈ 31,709,791,983.8 years Connection to the Age of the Universe: The duration (in years) of one quintillion seconds, or one exasecond is approximately 2.3 times the current age of the known universe and time since the Big Bang (which is approximately 14 billion years or approximately 4.4 × 10^17 seconds when converted into seconds). However, the age of the universe can be expressed as a fraction of an exasecond: approximately 0.44 exaseconds (Es) old. International System of Units (SI) Reference: In the International System of Units, the metric prefix exa- (E) represents one quintillion, or 10^18. So, one quintillion seconds can also be represented as one exasecond (Es), which comes from the SI prefix exa- (E) combined with the SI's base unit of time which is the second (s). More specifically, the complete official definition of an exasecond is: 10^18 seconds = 1 exasecond (Es) = 31.7 billion years - Exasecond is one quintillion seconds. So, in conclusion, one quintillion seconds is equivalent to approximately 31.7 billion years and can also be represented as one exasecond (Es).
