Calculadora de Notação Científica

Converta números de e para a notação científica.

Introdução

Scientific Notation Calculator — Convert numbers to and from scientific notation. Enter Number to get an instant, accurate result.

Fórmula

Converts a decimal number to a × 10ᵇ by dividing out powers of 10 until the coefficient a has a single non-zero leading digit; b is the base-10 exponent (floor of log₁₀|n|).

Passo a passo

  1. Enter the Number.
  2. Click Calculate to see your result instantly.

Exemplo do mundo real

Example: With Number = 123000, the Scientific Notation Calculator gives Coefficient: 1.23, Exponent: 5, Notation: 1.23 x 10^5.

Perguntas Frequentes

What is the coefficient range in scientific notation?
The coefficient is always between 1 and 10 (or −10 and −1 for negative numbers).
What if I enter 0?
Zero is returned as a coefficient of 0 with an exponent of 0.
What inputs does the Scientific Notation Calculator need?
You'll need to provide: Number. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Scientific Notation Calculator?
The Scientific Notation Calculator applies the formula exactly as calculated — Converts a decimal number to a × 10ᵇ by dividing out powers of 10 until the coefficient a has a single non-zero leading digit; b is the base-10 exponent (floor of log₁₀|n|). — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Scientific Notation Calculator free to use?
Yes, the Scientific Notation Calculator is completely free, requires no signup, and runs instantly in your browser.

Sobre a Calculadora de Notação Científica

The Scientific Notation Calculator uses a real, verifiable formula — Converts a decimal number to a × 10ᵇ by dividing out powers of 10 until the coefficient a has a single non-zero leading digit; b is the base-10 exponent (floor of log₁₀|n|). — so results are accurate every time, not an approximation.
