1. A unit of magnetic flux density equal to one thousandth of a gauss, used in physics and engineering.
Usage: technical; often abbreviated as mG

Examples

• The Earth's magnetic field at the surface is approximately 250 to 650 milligauss.
• The device measures magnetic fields in milligauss to detect anomalies.
• Sensitive equipment must be shielded from fields exceeding 10 milligauss.
• The laboratory calibrated its magnetometer using a standard of 100 milligauss.
• Exposure limits for workers near magnetic equipment are often set at several hundred milligauss.
