O ovom kalkulatoru
Scientific notation writes a number as a coefficient between 1 and 10 multiplied by a power of ten, and this scientific notation converter turns any value into that form along with E-notation, engineering notation, its order of magnitude, and the plain standard-form number. It also reads scientific input, so you can convert in either direction.
To build the coefficient, the decimal point is moved so a single non-zero digit sits in front of it; the number of places moved becomes the exponent. So 12,345 has its point shifted four places to give 1.2345 × 10⁴, and small numbers use a negative exponent — 0.00045 becomes 4.5 × 10⁻⁴. Engineering notation keeps the exponent to a multiple of three (matching kilo, mega and so on), rewriting 12,345 as 12.345 × 10³, and the order of magnitude is just that power of ten, 4 here.
Scientific notation is how very large and very small quantities are handled in physics, astronomy, chemistry and computing without writing long strings of zeros. Entering a value in E-notation such as 1.2e5 converts it straight back to the standard number 120000.
Česta pitanja
Kako se napiše broj u znanstvenom notiranju?
Pomaknite decimalnu točku tako da jedna ne nula cifra stoji ispred nje, a zatim pomnožite sa 10 na broj mjesta pomaknutih. 12,345 = 1,2345 × 104.
Što je e-notacija?
E-notation is how calculators display scientific notation: 1.2345 × 10⁴ is shown as 1.2345e+4, where the number after e is the power of ten.
Što je inženjerski zapis?
It is like scientific notation but the exponent is kept to a multiple of three, so it lines up with metric prefixes. 12,345 is written 12.345 × 10³.
Koji je redoslijed veličine broja?
To je moć deset u svom znanstvenom notatu — eksponent. Za 12,345 redoslijed veličine je 4.
Mogu li pretvoriti e-notaciju natrag u običan broj?
Yes. Type a value like 1.2e5 and the converter expands it to the standard form 120000.
Kako su vrlo mali brojevi napisane u znanstvenom notatu?
Koristi negativan eksponent. 0,00045 postaje 4,5 × 10−4, pomjeranje točke četiri mjesta udesno.
