Metric / SI

Kilogram

What is a kilogram?

The kilogram (kg) is the SI base unit of mass, defined by fixing the Planck constant h at 6.62607015E-34 J s.

Origin of the kilogram

From Greek 'khilioi' (thousand) plus 'gramma' (small weight).

Where it is used

The worldwide base unit of mass in science, commerce, and everyday life.

When and where it was developed

Adopted in 1795; redefined through the Planck constant on 20 May 2019.

Metric / SI

Exagram

What is a exagram?

An exagram (Eg) equals 10^15 kilograms, or one quintillion grams.

Origin of the exagram

From the SI prefix 'exa-' (from Greek 'hex', six, denoting the sixth power of 1000).

Where it is used

Confined to planetary- and atmospheric-scale mass discussions; never used in daily measurement.

When and where it was developed

The exa- prefix was adopted by the General Conference on Weights and Measures (CGPM) in 1975.

Kilogram to Exagram conversion formula

The relationship between kilograms and exagrams:

1 kg = 1e-15 Eg
1 Eg = 1e+15 kg

To convert kilograms to exagrams, multiply the value in kilograms by 1e-15. To reverse, multiply exagrams by 1e+15.

How to use this converter

Type a value into the calculator. The result in exagrams updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Exagram to Kilogram converter for the reverse direction.

Step-by-step: convert kilograms to exagrams

  1. Write down the value in kilograms (kg).
  2. Multiply that value by the factor 1e-15.
  3. The product is the equivalent value in exagrams (Eg).
  4. To reverse, multiply the exagram value by 1e+15.

Worked examples

Example 1 — Convert 1 kg to Eg:
1 × 1e-15 = 1e-15 Eg

Example 2 — Convert 100 kg to Eg:
100 × 1e-15 = 1e-13 Eg

Real-world example — Fabric purchase length

Two kilograms of fabric equals a value in exagrams essential for tailors and textile buyers sourcing material from international suppliers that quote in different units.

2 kg × 1e-15 = 2e-15 Eg

Real-world example — Maritime depth conversion

A 10-kilogram sounding depth converts cleanly into exagrams. Recreational divers and sailors translate between the two units whenever they read legacy charts against modern depth-sounder displays.

10 kg × 1e-15 = 1e-14 Eg

Real-world example — Reference scenario in case of fallback

Conversion between human-scale length units is the everyday workflow of architecture, athletics, and apparel design — three of the most common contexts that span metric and imperial systems.

1 kg × 1e-15 = 1e-15 Eg

Frequently asked questions

How many exagrams is 1 kilogram?
1 kilogram equals 1e-15 exagram.
How do I convert kilograms to exagrams?
Multiply the value in kilograms by 1e-15 to get exagrams.
How do I convert exagrams back to kilograms?
Multiply the value in exagrams by 1e+15, or use the Exagram to Kilogram converter.
How many exagrams is 100 kilograms?
100 kilograms equals 1e-13 exagrams, because 100 × 1e-15 = 1e-13.
