Sun, 07th Apr 2024: Exploring The Foundations of the Metric System

The Metric System, adopted internationally on May 20, 1794, is a decimal-based cohesive system of units for measuring various physical quantities. Let’s delve into its fundamental structure, focusing on base units and SI prefixes.

Seven Base Units in the International System of Units (SI)

Meter (m) for length:

The meter is the base unit of length, originally defined as one ten-millionth of the quadrant meridian (a line passing through Paris). Now it’s precisely defined as the distance traveled by light in a vacuum in 299,792,458 nanoseconds.

Kilogram (kg) for mass:

The kilogram is the base unit of mass, which was originally defined as the mass of a particular cylinder of platinum-iridium alloy. Now it’s defined as the mass that is equal to the mass of the International Prototype of the Kilogram, which is kept at the International Bureau of Weights and Measures in Sevres, France.

Second (s) for time:

The second is the base unit of time and was originally defined as 1/86,400 part of a mean solar day. Now it’s precisely defined as the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom.

Ampere (A) for electric current:

The ampere is the base unit of electric current and is defined as the constant current which, if maintained in two straight parallel conductors of infinite length and negligible cross-section, and placed 1 meter apart in a vacuum, would produce between these conductors an electromotive force of 2 × 10⁹ volts per meter.

5. Kelvin (K) for temperature:

The kelvin is the base unit of thermodynamic temperature, which is an absolute temperature scale. It was originally defined based on the triple-point of water. Now it’s defined in terms of the Planck constant, hbar, and the Avogadro constant, N₀.

6. Mole (mol) for amount of substance:

The mole is the base unit for the measurement of quantity of a substance. One mole contains exactly 6.022 × 10²³ particles (also known as Avogadro’s number).

7. Candela (cd) for luminous intensity:

The candela is the base unit of luminous intensity and is defined as the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 × 10¹² hertz and that has a radiant intensity in that direction of 1/683 watt per square centimeter.

SI Prefixes Used to Denote Multiples and Submultiples of the Base Units

The International System of Units (SI) employs prefixes that represent multiples and submultiples of base units. These prefixes, derived from Greek roots, include:

Powers of 10, from pico- (p) to exa- (E):

  • Pico- (p): pico is equal to 10⁻¹².
  • Nano- (n): nano is equal to 10⁻⁹.
  • Micro- (μ): micro is equal to 10⁻⁶.
  • Milli- (m): milli is equal to 10⁻³.
  • Kilo- (k): kilo is equal to 10³.
  • Mega- (M): mega is equal to 10⁶.
  • Giga- (G): giga is equal to 10⁹.
  • Tera- (T): tera is equal to 10¹².
  • Peta- (P): peta is equal to 10¹⁵.
  • Exa- (E): exa is equal to 10¹⁸.

These prefixes simplify expressing large or small quantities, making measurements more manageable and efficient.

Historical Development of Metric Systems in Various Countries


The origin of the metric system can be traced back to France, specifically during the French Revolution in the late 18th century. The revolutionary government, under the leadership of Napoleon Bonaparte, sought to create a uniform measurement system for their vast empire. Thus, in 1795, the new metric system was officially decreed and adopted as the standard unit of measurement throughout France and its territories.

United Kingdom

Despite the early adoption by France, the United Kingdom remained largely resistant to the metric system. The British had a strong attachment to their traditional imperial units of measurement, which were deeply ingrained in their culture and economy. However, in the late 19th century, under pressure from international trade, Britain began to gradually adopt metric measures for scientific and industrial purposes.

United States

In the United States, the metric system faced a similar resistance from the public and industry. However, in 1866, the U.S. Congress passed the Standard Weights and Measures Act, which called for the creation of a national standard for weights and measures. The Metric Conversion Act of 1867 further authorized the use of metric units alongside imperial ones. Yet, it wasn’t until the late 20th century that the U.S. began a more concerted effort towards full metrication.

Metrication Programs and the Transition to Fully Metric Societies

The transition to fully metric societies required substantial efforts through various metrication programs. In some cases, these were top-down initiatives driven by governments, while in others, grassroots movements played a more significant role. The International System of Units (SI), adopted in 1967, provided a unified framework for metric measurements and accelerated the adoption process.

Challenges Faced During the Adoption Process and Solutions Employed

The adoption of the metric system was not without challenges. One major challenge was the resistance from the public and industries that were deeply entrenched in traditional units of measurement. Another challenge was ensuring consistency and accuracy in conversion between old and new units. Solutions to these challenges included public education, the creation of standardized conversion tables, and the gradual phase-out of imperial units from everyday use.
