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.
Često postavljana pitanja
Kako se brojevi pišu u naučnom zapisu?
Pomaknite decimalnu tačku tako da jedna cifra koja nije nula sjedi ispred nje, a zatim pomnožite sa 10 broj mjesta pomaknutih. 12,345 = 1,2345 × 10⁴.
Šta 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.
Šta je inženjerska notacija?
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 red veličine broja?
To je stepen od deset u naučnom zapisu - eksponent.Za 12,345 red veličine je 4.
Mogu li pretvoriti E-notaciju nazad u običan broj?
Yes. Type a value like 1.2e5 and the converter expands it to the standard form 120000.
Kako se vrlo mali brojevi pišu u naučnoj notaciji?
0,00045 postaje 4,5 × 10⁻⁴, pomičući tačku četiri mjesta desno.
API — koristite ovaj kalkulator iz koda
Pozovi ovaj kalkulator kao slobodnu JSON krajnju tačku - nije potreban ključ. Pošalji vrijednosti polja ispod kao parametre upita ili JSON. Sve što izostavite koristi istu zadanu vrijednost kojom je ova stranica unaprijed popunjena; nepoznat parametar je 400, nikad tiha nula. Pročitajte cijelu API dokumentaciju →
