Measuring Tools

One full revolution of the thimble on a micrometer typically equals the pitch of the thread on the spindle, which is usually 0.5 mm. This means that each full rotation of the thimble will advance the spindle by 0.5 mm.

You need different tools these measurements.

For mass you want a scale or balance.

You can only use the same tool for length and volume (a ruler, caliper or similar) if the object you are measuring is a well defined solid with known geometric shape.

Otherwise you will have to perform a measuring experiment for example put the object you want to determine the volume of in a graduated cylinder, pour a known volume of liquid into the cylinder, read the volume and subtract to determine the object's volume.

Usually from stainless steel.

The first step is to find the zero error and hence the zero correction. Rotate the micrometer until the fixed and movable jaws contact each other - not too hard and not too soft but just right, you should geta feel for this. Rarely will a micrometer will read zero. You need to figure out the zero error. It may be positive or negative. If the zero error is positive then the zero correction is negative and vicevers. Now open the micrometer and insert the object to be measured and close the micrometer with ideally the same sense of pressure you felt when you found the zero error. Now read the micrometer. You add the zero correction to get the true value.

ruler, temperature, tape measure, graduated cylinder, linear measurements

Vernier callipers are made in various sizes. The range would depend on the size.

The most usual size is 0 - 150 mm

It is less than a micrometer but greater than a non vernier caliper or ruler.

• Very low freezing point (you can leave your spirit level outdoors in winter even in Finland)
• Low viscosity (the bubble moves freely and the same whether warm or cold)

quantity for measuring vernier caliper is what

• pH meter to measure the acidity
• ruler or caliper for linear dimensions
• tape measure for the circumference
• scale for the mass
• colorimeter for the hue or color
• thermometer for the temperature
• Geiger meter for the radioactivity
• ...

Certainly. Precision and accuracy do not mean quite the same thing.

All measuring tools need to be recalibrated from time to time against a standard.

For instance you can get a very precise reading from a micrometer or vernier gage but if it has not been correctly calibrated the reading will not be accurate.

Ovality and Taper Guages are used

To measure distance from 0 to about 30 feet.

It depends on what you are trying to measure. If you are measuring the length of a car, for example, any reading obtained using vernier callipers is likely to be totally useless.

The key is to select a tool that is appropriate to the task.

A vernier caliper.

A caliper would be the best tool for measuring the width of a pencil lead. It is precise and allows you to measure small dimensions accurately.

You would measure liquids with a graduated cylinder.
