The Vernier list count is a measurement technique used in precision instruments to determine the accuracy of measurements.

• The Vernier list count is used to measure the difference between the smallest division on the main scale and the smallest division on the Vernier scale.

• It helps in achieving more precise measurements by allowing the user to read measurements beyond the resolution of the main scale.

• The Vernier list c...read more

Micrometer list count refers to the number of divisions on the thimble of a micrometer.

• Micrometer list count is used to measure small distances with high precision.

• It is the number of divisions on the thimble of a micrometer.

• For example, a micrometer with a list count of 25 will have 25 divisions on the thimble.

• The smaller the list count, the more precise the measurement can be.

• Micrometers with list counts of 50 or mor...read more

The welding gas used in welding is a mixture of gases such as argon, carbon dioxide, helium, and oxygen.

• The type of welding gas used depends on the type of metal being welded and the welding process being used.

• Argon is commonly used for TIG welding of aluminum and stainless steel.

• Carbon dioxide is used for MIG welding of mild steel.

• Helium is used for TIG welding of thick materials.

• Oxygen is used for oxy-fuel welding an...read more

1 mm is equal to 1000 microns.

• Micron is a unit of measurement used to measure very small distances.

• It is equal to one-thousandth of a millimeter or 0.001 mm.

• Microns are commonly used in industries such as electronics, optics, and manufacturing.

• For example, the thickness of a human hair is about 100 microns.

• 1 mm is equal to 1000 microns.
