Nanovolts to Statvolts Converter

How to Convert Nanovolts to Statvolts

To convert a voltage measurement from nanovolts to statvolts, divide the voltage by the conversion factor. Since one nanovolt is equal to 3.3356 × 10^-12 statvolts, you can use this formula:

The voltage in statvolts is equal to the nanovolts divided by 2.9979 × 10¹¹.

How Many Statvolts Are in a Nanovolt?

There are 3.3356 × 10^-12 statvolts in one nanovolt.

What Is a Nanovolt?

The nanovolt (symbol: nV) is a unit of electric potential equal to one billionth (10⁻⁹) of a volt. The prefix “nano” denotes a factor of 10⁻⁹ in the International System of Units. Nanovolts are encountered in precision measurement, low-noise electronics, and fundamental physics research. Sensitive magnetometers, such as superconducting quantum interference devices (SQUIDs), can detect magnetic flux changes that produce signals in the nanovolt range. In materials science, thermoelectric voltages generated across junctions of different metals at very small temperature differences can be in the nanovolt range. Nanovolt-level measurements require specialised low-noise amplifiers and shielded environments to avoid interference from electromagnetic noise. In neuroscience, while typical EEG signals are in the microvolt range, some subthreshold neural signals and field potentials can approach nanovolt levels, pushing the limits of current measurement technology.

One nanovolt is equal to:

• 10⁻⁹ volts (V)
• 0.001 microvolts (μV)
• 10⁻⁶ millivolts (mV)
• 10⁻¹² kilovolts (kV)
• 3.3356 × 10⁻¹² statvolts (stV)
• 10 abvolts (abV)

What Is a Statvolt?

The statvolt (symbol: stV) is the unit of electric potential in the centimetre–gram–second (CGS) Gaussian and electrostatic (ESU) systems of units. One statvolt equals exactly 299.792458 volts — a value derived from the speed of light (c = 299,792,458 m/s). The statvolt arises naturally in the CGS Gaussian system, where the relationship between electric and magnetic quantities incorporates the speed of light directly into the unit definitions. The conversion factor 299.792458 is exactly c/(10⁶), where c is the speed of light in metres per second. Statvolts were used in theoretical physics, particularly in electrodynamics and plasma physics, before the widespread adoption of SI units. The CGS Gaussian system has the advantage that many electromagnetic equations take simpler forms (without factors of 4πε₀ or μ₀). Today, statvolts are mainly encountered in older physics literature, in some branches of plasma physics, and in theoretical work where the CGS Gaussian system simplifies calculations. The unit provides an interesting example of how the speed of light connects electric and magnetic units.

Understanding Voltage Units

Voltage (also called electric potential difference or electromotive force) is a measure of the work needed to move a unit electric charge from one point to another in an electric field. It is one of the most fundamental quantities in electricity and electronics, analogous to pressure in a water system.

Ohm’s law (V = I × R) relates voltage (V) to current (I) and resistance (R), and the power equation (P = V × I) connects voltage to electrical power. These relationships are the foundation of all electrical engineering.

Major Voltage Unit Systems

• SI units (V with metric prefixes): The volt (V) is the SI derived unit of electric potential. Standard metric prefixes produce nanovolts (nV), microvolts (μV), millivolts (mV), kilovolts (kV), megavolts (MV), and gigavolts (GV). Each prefix step is a factor of 1,000.
• CGS electrostatic unit — Statvolt (stV): The voltage unit in the Gaussian/ESU system. One statvolt equals exactly 299.792458 V, a factor derived from the speed of light. Used in some theoretical physics contexts.
• CGS electromagnetic unit — Abvolt (abV): The voltage unit in the EMU system. One abvolt equals exactly 10⁻⁸ V (10 nanovolts). An extremely small unit, primarily of historical interest.

Voltage in Everyday Life

• Batteries: AA/AAA cells = 1.5 V, 9 V battery, car battery = 12 V, smartphone = 3.7–4.2 V.
• Household mains: 120 V (North America, Japan) or 230 V (Europe, Asia, Africa) at 50 or 60 Hz AC.
• USB power: USB 2.0/3.0 = 5 V, USB-C PD = 5/9/15/20 V (up to 48 V in Extended Power Range).
• Power transmission: 110–765 kV for long-distance lines, 4–35 kV for local distribution.
• Lightning: 100–300 MV potential difference, 20,000–200,000 A peak current.
• Static electricity: Walking on carpet can generate 1–25 kV.

Converting Between Voltage Units

SI voltage conversions follow simple powers of 10: each metric prefix step (nano → micro → milli → base → kilo → mega → giga) is a factor of 1,000. For CGS units, the key factors are: 1 stV = 299.792458 V (from the speed of light) and 1 abV = 10⁻⁸ V (exact).

Tips for Voltage Conversions

• For SI prefix conversions (nV, μV, mV, V, kV, MV, GV), each step is a factor of 1,000. So 1 kV = 1,000 V = 1,000,000 mV, and 1 V = 1,000 mV = 1,000,000 μV.
• The statvolt factor (299.792458 V) comes from the speed of light: c = 299,792,458 m/s, and 1 stV = c/(10⁶) V. This is an exact value.
• The abvolt is exactly 10 nanovolts (10⁻⁸ V). This is a very small voltage — it takes 100 million abvolts to make 1 volt.
• The relationship between statvolts and abvolts involves c²: 1 stV = c² × 10⁻⁸ abV ≈ 2.998 × 10¹⁰ abV.
• When dealing with very large or very small numbers, scientific notation is helpful: 1 GV = 10⁹ V, and 1 nV = 10⁻⁹ V.
• Don’t confuse voltage (electric potential, measured in volts) with current (charge flow, measured in amperes) or resistance (opposition to current, measured in ohms). Voltage “pushes” current through resistance.
• In practice, kilovolts are the most common “large” voltage unit (power lines, X-rays), while millivolts and microvolts are common “small” units (sensors, biomedical signals).
