A triple beam balance accurately measures mass; however, often a scale that measures weight is used, and the mass is inferred. Mass is the measurement of the amount of matter present in an object. Weight is the measureme... More »

Scales are the most appropriate instrument for measuring mass on Earth. Mass and weight are not necessarily the same, even though the terms are sometimes used interchangeably. More »

There are many instruments used to measure length including rulers, tape measures, micrometers, gauges and vernier calipers. There are also instruments that make use of scientific principles to deduce length where it may... More »

A triple beam balance is an instrument used to obtain precise measurements of masses. The reading error of a standard triple beam balance is only 0.05 grams. More »

Spring scales measure the magnitude of forces, most commonly weight, which is the downward force of gravity on an object. It works from the principle laid down by Isaac Newton in his third law of universal motion, that f... More »

There is no direct conversion between these measurements because a milligram is a measure of mass and a teaspoon is a measure of volume. However, there are 0.00018 teaspoons in 1 milligram of salt, so 1 milligram divided... More »
