Convert Nanoamperes to Amperes
Convert Nanoamperes (nA) to Amperes (A) instantly and accurately.
Conversion Formula
A = nA × 1.000000000e-9
About Nanoamperes
The nanoampere (nA) equals 10⁻⁹ A, typical for reverse saturation currents of silicon diodes, quiescent supply currents of CMOS logic, and microelectrode measurements in analytical electrochemistry. A silicon p-n junction at room temperature has a saturation current of 1-10 nA; a well-designed op-amp input bias current is 1-100 nA; wearable biosensors commonly operate in the nanoampere range. 1 nA = 10⁻³ µA = 10³ pA.
About Amperes
The ampere (A) is the SI base unit of electric current, defined since 2019 by fixing the elementary charge e = 1.602 176 634 × 10⁻¹⁹ C. One ampere corresponds to approximately 6.241 × 10¹⁸ electrons passing a cross-section per second. Common benchmarks: a 60 W incandescent lamp draws 0.5 A at 120 V; household circuit breakers protect at 10-30 A; a car starter motor draws 100-200 A on cranking.
