meter-, metro-, metr-, -metrical, -metrically, -metron, -metric, -metrist, -meters, -metry, -metre

An instrument used for the measurement of magnetic flux or the lines of magnetic force arising from and found in the vicinity of a magnetized body.

An instrument designed specifically for the measurement of low temperatures.

An instrument for testing taste sensation by applying an electrical stimulus to the lingual mucosa.

An instrument that measures a small electric current by measuring the mechanical motion derived from electromagnetic or electrodynamic forces produced by the current.

Galvanometers can be used directly as ammeters, and are the core element of many ohmmeters and voltmeters.

The art or process of measuring the force of electric currents.

A gauge for measuring laughter

1. An extension of geometry conceived as taking time into account as the fourth dimension; the geometry of space-time.
2. Absolute geochronology, in which events are assigned (approximate) dates in relation to the present instead of to other events.
3. Measurement of geologic time, as through isotopic-radioactive decay.

1. Pertaining to, or according to the rules or principles of, geometry.
2. Determined by geometry; as, a geometrical solution of a problem.

Geometrical is often used in a limited or strictly technical sense, as opposed to mechanical; therefore, a construction or solution is geometrical which can be made by ruler and compasses; that is, by means of right lines and circles.

1. In a geometric fashion.
2. With respect to geometry.
3. According to the rules or laws of geometry.

1. The branch of mathematics that deals with points, lines, surfaces, and solids, and examines their properties.
2. A branch of mathematics that is concerned with the properties and relationships of points, lines, angles, curves, surfaces, and solids.
3. In nuclear medicine, any of the various arrangements between a radioactive source and a detector that affects the accuracy of counting or measurement.

1. The direct or indirect measurement or approximation of the temperatures at which geologic processes take place or have taken place.
2. The study of the earth's heat and temperatures, and their effects on geologic processes.
3. The study of the earth's heat and subsurface temperatures.
4. In geology, a mineral or aggregate of minerals whose presence defines the temperature range of limits within which the minerals were formed; also known as a geologic thermometer.

An instrument for measuring the number of red blood corpuscles in the blood.

The method depends on the differences of tint obtained by mixing a sample of the blood with sodium carbonate solution.

1. A device for measuring the strength of the tongue muscles.
2. An apparatus for estimating the contractile force of the tongue muscles.
3. An instrument for measuring the capacity of the tongue to resist pressure.
