Suhail Khan 7 years, 3 months ago

m², where "A" is the ampere (the SI unit of current) and "m" is the meter (the SI unit of distance). This has equivalents in other units used in SI including: where "N" is the newton (the SI unit of force), "T" is the tesla (the SI unit of magnetic flux density), and "J" is the joule (the SI unit of energy).
