ATRONOMY – ATROBIOLOGY & ETI (20) CALCULATOR
Kardashev Scale
A precise tool.
What is the Kardashev Scale & How does it work?
The Kardashev Scale, proposed by Nikolai Kardashev in 1964, classifies hypothetical extraterrestrial civilizations based on the amount of energy they can harness.
A Type I civilization can use all energy available on its home planet (~10^16 W), a Type II can capture the output of its star (~10^26 W), and a Type III can command the power of an entire galaxy (~10^36 W).
The scale is calculated using the formula below, where P is the total power in watts.
K = \frac{\log_{10}(P) – 6}{10}
K = Kardashev rating

Frequently Asked Questions
What is a Type I civilization on the Kardashev Scale?
A Type I civilization can harness all the energy available on its home planet, approximately 10^16 watts.
How does one calculate their Kardashev Scale rating?
Use the formula K = (log10(P) - 6) / 10, where P is the total power in watts.
What energy level does a Type II civilization require?
A Type II civilization can capture the output of its star, which is about 10^26 watts.
Can humans achieve a Kardashev Scale rating of 1?
Yes, human civilization is currently estimated to be around a 0.7 on the Kardashev Scale, with the potential to reach Type I in the future.
What does it mean to be a Type III civilization?
A Type III civilization can command the power of an entire galaxy, estimated at around 10^36 watts.
How long would it take for humans to reach a Type II civilization?
The time required is highly speculative and depends on advancements in technology and energy production methods.
Is there any real-world example of a Kardashev Scale rating being calculated?
While not officially recognized, SETI (Search for Extraterrestrial Intelligence) uses the scale to speculate about potential alien civilizations based on detectable signals or energy signatures.
