STEP 0: Pre-Calculation Summary
Formula Used
Number of Communicative Civilizations = (Rate of Formation of Suitable Stars*Fraction of Those Stars with Planets*Fraction of Earth sized Planets where Life Grows*Number of Earth-sized Worlds per Planetary System*Fraction of Life Sites where Intelligence Develops*Fraction of Communicative Planets*Lifetime of Communicating Civilizations)
Ncivilization = (R*fp*fl*ne*fi*fc*L)
This formula uses 8 Variables
Variables Used
Number of Communicative Civilizations - Number of Communicative Civilizations is the number of possible civilization maybe present in planet worthy of communication.
Rate of Formation of Suitable Stars - Rate of Formation of Suitable Stars is the speed at which the suitable stars or sun are formed.
Fraction of Those Stars with Planets - Fraction of Those Stars with Planets is the estimation of fraction of those stars which are communicative civilizations.
Fraction of Earth sized Planets where Life Grows - Fraction of Earth sized Planets where Life Grows is the part of earth sized planet where life exists and develops.
Number of Earth-sized Worlds per Planetary System - Number of Earth-sized Worlds per Planetary System is the no. of similar earth sized world per planetary system.
Fraction of Life Sites where Intelligence Develops - Fraction of Life Sites where Intelligence Develops is the part of earth sized planet where the life has developed intelligence.
Fraction of Communicative Planets - Fraction of Communicative Planets is the planets that communicates with other stars and planetary system.
Lifetime of Communicating Civilizations - Lifetime of Communicating Civilizations is the time period of the civilization which communicates.
STEP 1: Convert Input(s) to Base Unit
Rate of Formation of Suitable Stars: 24 --> No Conversion Required
Fraction of Those Stars with Planets: 7 --> No Conversion Required
Fraction of Earth sized Planets where Life Grows: 11 --> No Conversion Required
Number of Earth-sized Worlds per Planetary System: 6 --> No Conversion Required
Fraction of Life Sites where Intelligence Develops: 14 --> No Conversion Required
Fraction of Communicative Planets: 12 --> No Conversion Required
Lifetime of Communicating Civilizations: 25 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Ncivilization = (R*fp*fl*ne*fi*fc*L) --> (24*7*11*6*14*12*25)
Evaluating ... ...
Ncivilization = 46569600
STEP 3: Convert Result to Output's Unit
46569600 --> No Conversion Required
46569600 <-- Number of Communicative Civilizations

## What is METI factor?

the factor is defined as "the fraction of communicative civilizations with clear and non-paranoid planetary consciousness", or alternatively expressed, the fraction of communicative civilizations that actually engage in deliberate interstellar transmission.
The METI factor is somewhat misleading since active, purposeful transmission of messages by a civilization is not required for them to receive a broadcast sent by another that is seeking first contact. It is merely required they have capable and compatible receiver systems operational; however, this is a variable humans cannot accurately estimate.
