Don't ask us how they found the mass of the Earth, as there isn't any scale big enough to weigh the entire planet. As for the circumference, talk to Eratosthenes. Suppose that you've taken up astronomy recently and would like to know the gravitational force acting between the Earth and the Moon. For the calculations, we need the masses of the two objects (denote the Earth's by M₁ and the Moon's by M₂) and the distance between them (denoted by R). We have: For instance, take the number 154.37. It is in its standard form in the decimal base. That means 1 is the hundreds digit, 5 is that of tens, 4 of ones, 3 of tenths, and 7 of hundredths. Having the number written the way it is, makes us see it as a whole, and we don't really think of the individual digits, do we?

In addition to the A-series, there are also the B and C series. The B series extends the range of paper sizes available in the A-series, while the C series is limited to envelopes. As you can see, we had five digits, so we got five terms. What is more, consecutive digits appear in consecutive summands; we simply add a few zeros in the correct places to make it all jump to the right spot when we add it all up. This time, we indeed see the digits as the first factors in each multiplication. Moreover, the second factors have a lot in common - they consist of a single 1 with some zeros (possibly none). The factor 2.54 is the result from the division 1 / 0.393701 (centimeter definition). Therefore, another way would be:

An inch (symbol: in) is a unit of length. It is defined as 1⁄12 of a foot, also is 1⁄36 of a yard. Though traditional standards for the exact length of an inch have varied, it is equal to exactly 25.4 mm. The inch is a popularly used customary unit of length in the United States, Canada, and the United Kingdom. Definition of centimeter Proper fraction button is used to change a number of the form of 9/5 to the form of 1 4/5. A proper fraction is a fraction where the numerator (top number) is less than the denominator (bottom number). Now that we've seen how to write a number in standard form, it's time to convince you that it's a useful thing to do. Of course, we know that you're most probably learning all of this for the pure pleasure of grasping yet another part of theoretical mathematics, but it doesn't hurt to take a look at physics or chemistry from time to time. You know, those two minor branches of mathematics. and the circumference is... actually, the 40,075 km doesn't look that bad, does it? Well, we could use a length converter and change it to 4.0075 × 10⁴ km, but is it better that way? If we needed to change it to millimeters, then maybe it'd be a better idea, but the kilometer form seems perfectly usable. We said that the number b should be between 1 and 10. 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 could, however, convert it to standard form by saying that:

Now, this looks even worse than the previous example; it doesn't have commas in between! Thankfully, there are tools - like our standard form calculator - to make our lives easier. So, what is the standard form of the above numbers? In the first section, we mentioned that the standard form converter is most useful when we're dealing with very large or very small numbers. So, why don't we take one object from each side of the spectrum: a planet and an atom. Non-Americans often refer to the standard form in math in connection with a very different topic. To be precise, they understand it as the basic way of writing numbers (with decimals) using the decimal base (as opposed to, say, the binary base), which we can decompose into terms representing the consecutive digits. The expanded form is a way to write a number as a sum, each summand corresponding to one of the number's digits. In our case, the sum would be: For our non-American friends out there, the standard form is usually quite a different thing. 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. This notion is connected to the expanded form, and we explain it all in detail in the dedicated section. 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..."Welcome to the standard form calculator, where we'll learn how to write a number in standard form. "What is the standard form?" Well, we'll get to the standard form definition soon enough. 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. It's quite troublesome to write all the zeros of a number in every line of our calculations. Preferably, we can use standard form exponents and write the same thing with just a few symbols. That's why we made this standard form converter – to help you with just that. Proper fraction button and Improper fraction button work as pair. When you choose the one the other is switched off. The paper formats that are available within the ANSI are comparable to those on offer in the ISO standard in that dividing a sheet in half will generate two sheets in the next size. Before 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: which is the number we had initially but with the point two places to the right. This movement by 2 is shown by the power in the standard form exponents.

Converting numbers into numeric form can be very beneficial in a range of disciplines including engineering, mathematics, and computing. In a calculator or computer, E or e, which stand for exponential, are employed to denote the power of 10. E NotationAnyway, if scientists had to write all of those zeros every time they calculated something about our planet, they'd waste ages! It's much easier to recall how to write a number in standard form and say that the mass of Earth is, in fact, This free scientific notation calculator and converter can perform a range of operations in scientific notation, including adding, subtracting, multiplying, and dividing numbers. It can also convert real decimal numbers to scientific notation, and vice versa. F = 0.00000000006674 N·m²/kg² × 5,972,000,000,000,000,000,000,000 kg × 73,480,000,000,000,000,000,000 kg / (384,400,000 m)². To find the resulting product, find the sum of 3 individual product of multiplier and multiplicand. There is a valuable lesson here: writing numbers in standard form is not always the way to go. It's all about simplicity of notation, but, at the end of the day, it pretty much boils down to a matter of personal preference (or your teacher's if you're writing a test).

To calculate a inch value to the corresponding value in centimeters, just multiply the quantity in inches by 2.54 (the conversion factor). Inches to centimeters formulaeArrange the 4-digit multiplicand and 3-digit multiplier for long multiplication method, multiply the multiplicand by Least Significant Digit (LSD) of multiplier and the product underneath to the line in the way that the Ones’s place value of multiplicand and One’s place value of product of LSD of multiplier and whole multiplicand should be vertically aligned in a straight line. We've spent quite some time together with the standard form calculator, enough to know that we can't leave the answer like this. We haven't learned how to write a number in standard form for nothing. But there's more! We have multiplication and division in the formula, and the standard form exponents make these two operations very easy to calculate. By the well-known, well-remembered, and totally not forgotten the moment the test was over formulas, multiplying two powers with the same base is the same as adding the exponents, while dividing corresponds to subtracting them. In other words, if we separate the 10s to some powers from the other numbers, we'll get:
