Technical English-Unit-6-Measuring

1. Unit (6) Measuring
1. The basis of science and technology is measurement.
2. Experiments involve measuring weight, volume, length, time, temperature, and pressure.
Measuring Units:
1. The unit for weight is the kilogram (KG).
2. The unit for length is the meter (M).
3. The unit for time is the second (S).
4. The unit for temperature is Celsius (C).
5. The unit for volume is the liter (L).
6. The unit for pressure is the millibar (MB).

2. Measuring Instruments:
1. Calipers are used to measure small widths and diameters.
2. A travelling microscope is used to measure small lengths.
3. A top-pan balance or a spring balance can be used to measure mass or weight.
4. Analogue and digital stopwatches are used to measure time.
5. Thermometers are used to measure temperature.
6. Barometers are used to measure atmospheric pressure.
