Weights and Measures

The meter (m) is defined by taking the fixed numerical value of the speed of light in vacuum c to be 299,792,458 when expressed in the unit m s−1, where the second is defined in terms of ∆νCs.

The meter was once defined by a physical artifact - two marks inscribed on a platinum-iridium bar. The Length - Evolution from Measurement Standard to a Fundamental Constant explains the evolution of the definition of the meter. Follow these changes over time in the NIST Length Timeline.

From the meter, several other units of measure are derived such as the:

  • unit of speed is the meter per second (m/s). The speed of light in vacuum is 299 792 458 meters per second.
  • unit of acceleration is the meter per second per second (m/s2).
  • unit of area is the square meter (m2).
  • unit of volume is the cubic meter (m3). The liter (1 cubic decimeter), although not an SI unit, is accepted for use with the SI and is commonly used to measure fluid volume.

FAQ: When did the metric redefinition of the inch occur?

In 1958, a conference of English-speaking nations agreed to unify their standards of length and mass, and define them in terms of metric measures. The American yard was shortened and the imperial yard was lengthened as a result. The new conversion factors were announced in 1959 in Federal Register Notice 59-5442 (June 30, 1959), which states the definition of a standard inch: The value for the inch, derived from the value of the Yard effective July 1, 1959, is exactly equivalent to 25.4 mm.

Check Points (if not specified, we adhere to our quality policy)

Gage ID is the unique identifier you use to identify the specific piece of equipment.

Calibration Cycle is the interval between calibrations.

 We use this information to provide a sticker for the calibrated instrument to show when it was calibrated and when you want it calibrated again.

 

 

 

 

YES!

Please include power cords, leads, and any accessories necessary for us to perform the calibration.

 

 

All ISO 17025 accredited calibrations are traceable through NIST or another NMI(National Metrology Institute) to the SI Unit. 

Calibration certificates include as-found data, as-left data, and measurement uncertainty.
