PART I
FUNDAMENTAL UNITS

The fundamental electrical units are the units agreed as such at an international conference on electrical units and standards held in London in October, 1908 (the magnitude thereof being determined on the electromagnetic system of measurement, with reference to the centimetre as the unit of length, the gram as the unit of mass and the second as the unit of time), and comprising—

      (a)   the ohm, the unit of electrical resistance, the value thereof being one thousand million in terms of the centimetre and the second;

      (b)   the ampere, the unit of electrical current, the value thereof being one tenth in terms of the centimetre, the gram and the second;

      (c)   the volt, the unit of electromotive force, the value thereof being one hundred million in terms of the centimetre, the gram and the second.

PART II
DENOMINATIONS OF STANDARDS

1. Electrical Resistance. A standard of electrical resistance denominated one ohm, agreeing in value with the limits of accuracy specified in Part III with that of the fundamental unit in paragraph (a) of Part I, and being the resistance between the copper terminals of the instrument marked “Board of Trade Ohm Standard Verified 1894 and 1909” to the passage of an unvarying electrical current, when the coil of insulated wire forming part of the instrument aforesaid is in all parts at a temperature of fourteen decimal nine degrees centigrade.

2. Electrical Current. A standard of electrical current denominated one ampere, agreeing in value within the limits aforesaid with that of the fundamental unit in paragraph (b) of Part I, and being the current which is passing in and through the coils of wire forming part of the instrument marked “Board of Trade Ampere Standard Verified 1894 and 1909” when, on reversing the current in the fixed coils, the change in the forces acting on the suspended coil in its sighted position is exactly balanced by the force exerted by gravity in Teddington in the United Kingdom upon the iridioplatinum weight marked A and forming part of the said instrument.

3. Electrical Pressure. A standard of electrical pressure denominated one volt, agreeing in value within the limits aforesaid with that of the fundamental unit in paragraph (c) of Part I, and being one hundredth part of the pressure which, when applied between the terminals forming part of the instrument marked “Board of Trade Volt Standard Verified 1894 and 1909 and 1948”, causes that rotation of the suspended portion of the instrument which is exactly measured by the coincidence of the sighting wire with the image of the fiducial mark A before and after the application of the pressure, and with that of the fiducial mark B during the application of the pressure, these images being produced by the suspended mirror and observed by means of the eyepiece.

4. The coils and instruments referred to herein are deposited at the National Physical Laboratory at Teddington, Middlesex, in the United Kingdom.

PART III
LIMITS OF ACCURACY

The limits of accuracy attainable in the use of the standards denominated in Part II are—

      (a)   for the ohm, within one hundredth part of one per centum;

      (b)   for the ampere, within one tenth part of one per centum;

      (c)   for the volt, within one tenth part of one per centum.

PART IV
DERIVED ELECTRICAL UNIT OF ENERGY

The derivation of the kilowatt hour as the lawful electrical unit for the measurement of electricity shall be from the fundamental units described in Part I. Thus one watt (the practical unit of power) shall be equal to the amount of energy expended per second by an unvarying current of one ampere with a steady applied voltage of one volt. For the purpose of expressing watts in terms of voltage and resistance, or current and resistance, the steady voltage applied to a constant resistance shall be equal to the unvarying current in amperes multiplied by the value of the resistance in ohms.

In an alternating-current circuit the product of the instantaneous value of the amperes and the volts represents the instantaneous value of the power and the algebraic mean value of the instantaneous values over one second shall be the power in watts provided that the frequency is fifty cycles per second. One watt-hour shall be equal to the energy expended in one hour when the power is one watt, and a kilowatt-hour shall be equal to one thousand watt-hours.
