Home > Orders of magnitude (power)

This page lists examples of the power in watts produced by various different sources of energy. They are grouped by orders of magnitude, and each section covers three orders of magnitude, or a factor of one thousand.

1 1 yoctowatt

2 1 zeptowatt

• ~10 zW - approximate power of Galileo space probe's radio signal as received on earth by 70 meter DSN antenna.

3 1 attowatt

• 1 aW - approximate power scale at which operation of nanoelectromechanical systems is overwhelmed by thermal fluctuations.[1]

4 1 femtowatt

• 10 pW (-110 dBm) - approximate lower limit of power reception on digital spread-spectrum cell phones

5 1 picowatt

• 1 pW - average power consumption of a human cell
• 2.5 pW - Sound intensity per square centimeter for average human threshold of hearing at 1000Hz; 1 phon or 0 dB SPL

6 1 nanoNano is a prefix (symbol n in the SI system of units denoting a factor of 10-9. It is often used in prefixing time and length units encountered in electronics and computer systems, like 30 nanoseconds (symbol ns) and 100 nanometers (nm). It was confirmedwatt

7 1 microMicro is a SI prefix in the SI system of units denoting a factor of 10−6 (one millionth). The symbol for it is the micro sign (µ). Confirmed in 1960, the prefix comes from the Greek κ (transliterated: mik''ros , meaning small''. More generallywatt

• 1 μW - approximate consumption of a quartzFor other uses of this word, see Quartz (disambiguation). Milk quartz rock Quartz is the most abundant mineral on Earth (about 12% vol. It has a hexagonal crystal structure made of trigonal-crystallized silica (silicon dioxide, SiO), with a hardness of 7 wristwatch
• 15 μW - estimated power of an antThe antpower is a unit of power, named by analogy with the more usual horsepower. It can be estimated that one ant can generate 15 W (on the basis that one strong ant can lift 50 times its weight). It follows that it takes 67 million ants to generate a ki

Orders of magnitudeAn order of magnitude is the class of bigness, the class of size, the class of magnitude, of any amount, where each separate class contains ten times larger amounts than the one before. It is generally used to make very approximate comparisons.
