# 1 erg is equal to how many joules

Use this page to learn how to convert between joules and ergs. A joule is equal to the work done when a current of 1 ampere is passed through a resistance of 1 ohm for 1 second. By another definition, the joule is equal to the energy required to pass an electric current of one ampere through a one ohm resistor for one second. 1 joule to erg = 10000000 erg. On the surface of the Earth, it takes about 0.98 ergs to lift a 1 milligram object by 1 centimeter. The erg has not been a valid unit since 1 January 1978[13] when the EEC[clarification needed] ratified a directive of 1971 which implemented the International System (SI) as agreed by the General Conference of Weights and Measures. Conversion of 1 joule into erg by a very simple method. How many mJ in 1 joule? 1 joule is equal to 10000000 erg. Note that rounding errors may occur, so always check the results. Exchange reading in ergs unit erg into joules unit J as in an equivalent measurement result (two different units but the same identical physical total value, which is also equal to their proportional parts when divided or multiplied). unit of ..." and requested that the word erg or ergon be strictly limited to refer to the C.G.S.
