About the CGS Unit Converter
The CGS unit converter translates centimetre–gram–second units into SI units and back for force (dyne), pressure (barye), energy (erg) and mass. CGS units remain common in astrophysics, electromagnetism and older scientific papers. Key relationships are 1 N = 10⁵ dyn, 1 J = 10⁷ erg and 1 Pa = 10 Ba.
How to use it
- 1Choose the quantity: force, pressure, energy or mass.
- 2Enter the value and choose the from and to units.
- 3Read the converted value.
- 4Copy, share or print the result with the buttons below it.
Worked example
5 × 10⁶ erg ÷ 10⁷ = 0.5 J, and 250,000 dyn = 2.5 N.
How it works
CGS system
CGS uses centimetres, grams, and seconds as base units. SI uses metres, kilograms, and seconds. CGS is still used in astrophysics, electromagnetism, and some engineering fields.
Key: 1 N = 10⁵ dyn · 1 J = 10⁷ erg · 1 Pa = 10 Ba.
Common use cases
- Reading older physics papers
- Astrophysics calculations
- Physics homework
Frequently asked questions
A:1 dyne = 10⁻⁵ N = 0.00001 N.
A:1 erg = 10⁻⁷ J. The energy needed to lift 1 gram by about 0.1 mm.
