# Engineering Notation Calculator

Our **engineering notation calculator** is a convenient tool to *convert any decimal value* into **engineering notation**. If you are working with *very large* and *very small* numbers, engineering notation is a **more compact and less error-prone** method of representation. Keep reading, and we'll tell you **what engineering notation is** all about, **what the prefixes are** in engineering notation, and **how to convert to engineering notation**.

## What is an engineering notation?

**Engineering notation** is a version of scientific notation commonly *used by engineers* to represent numbers. For **engineering notation**, the exponent of ten is *always* a **multiple of three** and has its own SI prefix. Let's see how it works by taking the number **65,000**. To convert it to **engineering notation**:

- Divide the 65,000 into the
**precision part**and the**magnitude part**(the power of ten). The**65,000**will be**65 × 10**(65 times 10 to the 3rd power, which is^{3}*times a thousand*). - Substitute a
*multiple of three for the exponent*using the appropriate**engineering notation prefix**. Look at the**engineering notation chart**below:

Name/Symbol | Multiplier | |
---|---|---|

yocto (y) | 10 | |

zepto (z) | 10 | |

atto (a) | 10 | |

femto (f) | 10 | |

pico (p) | 10 | |

nano (n) | 10 | |

micro (μ) | 10 | |

milli (m) | 10 | |

kilo (k) | 10 | |

Mega (M) | 10 | |

Giga (G) | 10 | |

Tera (T) | 10 | |

Peta (P) | 10 | |

Exa (E) | 10 | |

Zetta (Z) | 10 | |

Yotta (Y) | 10 |

Thus, **65,000 volts** will be simply **65 kilovolts**. Similarly, the **0.000073 farads** could be written as 73 × 10^{-6} farads or **73 μF (microfarads)** using the engineering notation prefix *"micro"* (μ) for 10^{-6}.

## How to use our engineering notation calculator?

Using the **Omni's engineering notation calculator** to convert to engineering notation is extremely *easy* and *convenient*; you just have to:

**Enter your number**in decimal form or with an exponent (e), e.g., 3e-7 meters.- You can also use
**scientific notation**with multiples of 10, for example, 3 × 10^{-7}. - Use "Advanced Mode" to modify
**significant numbers**. This is the number of digits in a value that is*reliable and necessary*to indicate the quantity of something. The default value is set to 10. - The engineering notation calculator will return a result of
**300 × 10⁻⁹ m**or**300 nm (300 nanometers).**

## FAQ

### How can I write 0.0046 grams in engineering notation?

**4.6 mg** or, equivalently, **4.6 milligrams**. We will write 0.0046 as **4.6 × 10 ^{-3}** and know that the

**prefix for 10**is

^{-3}**m (milli)**.

### How can I multiply 15,000 by 0.000004 in engineering notation?

To do it:

- Write down 15,000 as
**15 kilos**(15 × 10^{3}) and 0.000004 as**4 micros**(4 × 10^{-6}). **Multiply the precision parts**and add the**exponents**, i.e. 15 kilos by 4 micros will be**60 milli**, because 10^{3}× 10^{-6}= 10^{-3}.
