Convert X-unit to chain (US survey)

Please provide values below to convert X-unit [X] to chain (US survey) [ch (US)], or Convert chain (US survey) to X-unit.

1 X = 4.9813e-15 ch (US). To convert X-unit to chain (US survey), multiply the value by 4.9813e-15; to go the other way, divide by it (1 ch (US) = 2.0075e+14 X). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Quick Reference

  • 1 X = 4.9813e-15 ch (US)
  • 1 ch (US) = 2.0075e+14 X
  • 10 X = 4.9813e-14 ch (US)
  • 100 X = 4.9813e-13 ch (US)



How to Convert X-Unit to Chain (Us Survey)

1 X = 4.98129919191436e-15 ch (US)

Example: convert 15 X to ch (US):
15 X = 15 × 4.98129919191436e-15 ch (US) = 7.47194878787153e-14 ch (US)

X-Unit

An X-unit is a unit of length approximately equal to 1.002 x 10⁻¹³ meters.

History/Origin

The X-unit was proposed by the Swedish physicist Manne Siegbahn in 1919 for measuring the wavelengths of X-rays and gamma rays.

Current Use

The X-unit has been largely replaced by the angstrom and the picometer.


Chain (Us Survey)

A U.S. survey chain is a unit of length equal to 66 U.S. survey feet.

History/Origin

The U.S. survey chain is based on the U.S. survey foot, which was slightly different from the international foot. The use of survey units was officially phased out in 2022.

Current Use

The U.S. survey chain was used for land surveying in the United States.
