The 20 SI prefixes are pre-symbols, used to form decimal multiples and submultiples of SI units. In long scale Billion prefix (10 12) is tera, Trillion prefix (10 18) is exa, Billionth prefix (10-12) is pico, Trillionth prefix (10-18) is atto, and so on. Example. For example kilometre (km), kilo means a thousand times. The Sun has a Mass of 1.988 × 10 30 kg. MEANINGS. For example: A 100 watt light bulb uses 0.1 kilowatts each hour. This is almost the same as 10 cubed, or 1000. As is consistent with SI units, the prefix kilo- means that a kilowatt equals one thousand watts or one thousand joules per second. Another example is millimetre (mm), where milli means thousandth part of something.. Convert 10kW to electrical horsepower: P (hp) = 10kW / 0.746 = 13.405 hp . A binary prefix indicates multiplication by a power of two. Prefixes In Computing Prefixes K,M,G,T,P (kilo,mega,giga,tera,peta) are commonly used in computing, where they â¦ SI prefixes. DICTIONARY.COM; THESAURUS.COM; MEANINGS. This has prompted the use of the metric prefixes kilo, mega, and giga to also denote the powers of 1024 which is common in information technology with the unit of digital information, the byte. gads The base unit of the kilowatt is the watt, which was named after Scottish inventor James Watt. One metric horsepower is equal to 0.73549875 kilowatts: 1 hp(M) = 735.49875 W = 0.73549875 kW. To put it simply, this means it measures the number of kilowatts you use over time. Kilo definition, kilogram. Definition: A kilowatt (symbol: kw) is a unit of power in the International System of Units (SI). Within the field of computer science, the prefix "kilo" means 2 to the 10th power, or 1024. Kilowatts to metric horsepower. Spelling out scientific notation numbers can be a mouthful. We have words that express the very large and the very small. Because the SI prefixes strictly represent powers of 10, they should not be used to represent powers of 2. Scientific notation is a useful means to write out very large or very small numbers using powers of ten. To alleviate this ambiguity, prefixes for binary multiples have been adopted by the International Electrotechnical Commission (IEC) for use in information technology. See more. Contents: SI prefix calculator and SI prefix table. The tenth power of 2 (2 10) has the value 1024, which is close to 1000. It would take 10 hours for the light to consume 1 kWh of energy. Kilowatt. 10 2 means 10 × 10 = 100 (It says 10 is used 2 times in the multiplication) Example: ... "Powers of 10" is a very useful way of writing down large or small numbers. The number 5 x 10 6 could be said âfive times ten to the sixâ, but it is easier to say âfive millionâ. Emoji; Slang; Acronyms; Pop Culture; ... a Greek combining form meaning âthousand,â introduced from French in the nomenclature of the metric system ... (that is, 1,024), which is the power of 2 closest to 1,000, as in kilobyte. So the power conversion of kilowatts to horsepower is given by: P (hp) = P (kW) / 0.746. How to Convert Units With Prefixes: 14 Steps (with Pictures) The unit symbol for "kilo" within the International System of Units is "k." "Kilo" was introduced by France into the metric system in 1799. If your energy company charges you a rate of \$0.10 for each kWh, you would pay \$0.10 to use a light every 10 hours. Thus, one kilobit, or 1 kbit, is 1000 bit and not 2 10 bit = 1024 bit. In the metric system of measurement, designations of multiples and subdivision of any unit may be arrived at by combining with the name of the unit the prefixes deka, hecto, and kilo meaning, respectively, 10, 100, and 1000, and deci, centi, and milli, meaning, respectively, one-tenth, one-hundredth, and one-thousandth.
