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. 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. A binary prefix indicates multiplication by a power of two. Definition: A kilowatt (symbol: kw) is a unit of power in the International System of Units (SI). Another example is millimetre (mm), where milli means thousandth part of something.. This is almost the same as 10 cubed, or 1000. For example: A 100 watt light bulb uses 0.1 kilowatts each hour. 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. Scientific notation is a useful means to write out very large or very small numbers using powers of ten. For example kilometre (km), kilo means a thousand times. See more. Within the field of computer science, the prefix "kilo" means 2 to the 10th power, or 1024. It would take 10 hours for the light to consume 1 kWh of energy. The number 5 x 10 6 could be said âfive times ten to the sixâ, but it is easier to say âfive millionâ. The tenth power of 2 (2 10) has the value 1024, which is close to 1000. Convert 10kW to electrical horsepower: P (hp) = 10kW / 0.746 = 13.405 hp . How to Convert Units With Prefixes: 14 Steps (with Pictures) The 20 SI prefixes are pre-symbols, used to form decimal multiples and submultiples of SI units. Kilowatts to metric horsepower. We have words that express the very large and the very small. To put it simply, this means it measures the number of kilowatts you use over time. Because the SI prefixes strictly represent powers of 10, they should not be used to represent powers of 2. The base unit of the kilowatt is the watt, which was named after Scottish inventor James Watt. Kilo definition, kilogram. Spelling out scientific notation numbers can be a mouthful. As is consistent with SI units, the prefix kilo- means that a kilowatt equals one thousand watts or one thousand joules per second. Kilowatt. To alleviate this ambiguity, prefixes for binary multiples have been adopted by the International Electrotechnical Commission (IEC) for use in information technology. SI prefixes. DICTIONARY.COM; THESAURUS.COM; MEANINGS. One metric horsepower is equal to 0.73549875 kilowatts: 1 hp(M) = 735.49875 W = 0.73549875 kW. 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. Contents: SI prefix calculator and SI prefix table. Emoji; Slang; Acronyms; Pop Culture; ... a Greek combining form meaning âthousand,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. Prefixes In Computing Prefixes K,M,G,T,P (kilo,mega,giga,tera,peta) are commonly used in computing, where they â¦ Example. The Sun has a Mass of 1.988 × 10 30 kg. 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. The unit symbol for "kilo" within the International System of Units is "k." "Kilo" was introduced by France into the metric system in 1799. gads So the power conversion of kilowatts to horsepower is given by: P (hp) = P (kW) / 0.746. MEANINGS.
