Scientific Notation and E notation

Scientific notation is the way to easily handle very large numbers or very small numbers. E notation is a variation of this and is used in computers, calculators and this web page.

Example 1:
Ordinary decimal notation: 100
Scientific notation: 1 x 102 or 1.00 x 102 (sometimes zeros are left to define precision)
E notation: 1e2 or 1.00e2 (sometimes zeros are also left to define precision)

Example 2:
Ordinary decimal notation: 1000
Scientific notation: 1 x 103 or 1.000 x 103 (sometimes zeros are left to define precision)
E notation: 1e3 or 1.00e3 (sometimes zeros are also left to define precision)

Example 3:
Ordinary decimal notation: 0.100160
Scientific notation: 1.0061 x 10-1 or 1.00160 x 10-1 (sometimes zeros are left to define precision)
E notation: 1.0016e-1 or 1.00160e-1 (sometimes zeros are also left to define precision)

Example 4:
Ordinary decimal notation: 0.0002
Scientific notation: 2 x 10-4
E notation: 2e-4

Using this Conversions Page


Unlike many other conversions tools on the web, this page offers a very fast and comprehensive set javascript-based converters. No need to select from cumbersome drop-down menus. Get units simultaneous converted for a particular category of measurement.

Example:

Convert the weight of 150 pounds to kilograms:

Step 1:
  Highlight the current value inside the box corresponding to the unit you have to convert. In this case it is pounds (lbs).  

Step 2:
  Type in 150 over the highlighted value and instantly read the answer for kilograms (kg). It shows 68.038855 which you can round up as you wish. So if you would like to round it to the nearest pound the answer will be 68 kilograms. In order to leave the precision up to the user, several digits will always be displayed for the results. Notice you get all the other units as well!  

Note that all the unit abbreviations are shown on the right vertical column of this page.
