In other words, we move the point one place to the right. If we take a number, say, 12,345.6789, and multiply it by 10, we'll get And that is exactly what the standard form exponents are for. , that separates the digits of the number by one place, which is equivalent to 10 to the power of one. What we've done above is basically move the point. We could, however, convert it to standard form by saying that: This means that, for example, 1.36 × 10⁷ or 9.81 × 10⁻²³ are in standard form, but 13.1 × 10¹² isn't because 13.1 is bigger than 10. We said that the number b should be between 1 and 10. Now, back to the question of the hour, "What does standard form mean?"īefore we give some examples of writing numbers in standard form in physics or chemistry, let's recall from the above section the standard form math formula: In that case, check out our quadratic formula calculator, but be sure to come back to us whenever you get the chance! Warning: There is a possibility that you've come across this standard form calculator in search of different ways of writing a quadratic equation. Also, note how you can switch between the two variants in the advanced section by choosing the appropriate option in the field " Have the calculator use." This notion is connected to the expanded form, and we explain it all in detail in the dedicated section. Outside of the USA (especially in the UK), we say that a number is in its standard form if it's a single value that involves no arithmetic operations whatsoever. That's why we made this standard form converter – to help you with just that.įor our non-American friends out there, the standard form is usually quite a different thing. Preferably, we can use standard form exponents and write the same thing with just a few symbols. It's quite troublesome to write all the zeros of a number in every line of our calculations. But let's just say that standard form in math and physics (quite often called scientific notation) is a neat way of dealing with very large or very small values. "What is the standard form?" Well, we'll get to the standard form definition soon enough. Welcome to the standard form calculator, where we'll learn how to write a number in standard form.
