Kilogauss to Tesla: A Comprehensive Guide for Understanding Magnetic Field Strength

Introduction

Magnetic field strength is a fundamental aspect of electromagnetism, influencing numerous scientific and technological applications. Two commonly encountered units for measuring magnetic field strength are kilogauss (kG) and tesla (T). This article aims to provide a comprehensive guide on converting between these units, understanding their significance, and exploring their applications.

Conversion Between Kilogauss and Tesla

To convert kilogauss to tesla, multiply the kilogauss value by 10. Conversely, to convert tesla to kilogauss, divide the tesla value by 10.

1 kG = 10 T
1 T = 0.1 kG
