Why are multiples and submultiples of SI units used?

Sometimes the size of the SI unit is either too small or too big to measure a certain quantity. For example a metre is too small a unit to measure the distance between two cities and too big a unit to measure the thickness of a wire. Hence multiples and submultiples of units are required.

What are submultiples of a unit give three examples?

For representing smaller distances or lengths, we use dm (decimetre) , cm(centimetre) and mm (millimetre) . These are called the submultiples of Metre.

### What are the Submultiples of length?

Submultiples are the units of measurement which are smaller than the meter. They are the decimeter, the centimeter, and the millimeter.

What do you mean by Submultiples?

#### What are the Submultiples?

What are multiples and submultiples of measurement?

Multiples are factors used to create larger forms whereas submultiples are factors used to create smaller forms of the SI units. For example, a centimetre is a submultiple and kilometre is a multiple of a metre. Solve any question of Units And Measurements with:- Patterns of problems.

What are the Submultiples of second?

Multiples of seconds are usually counted in hours and minutes. Fractions of a second are usually counted in tenths or hundredths. In scientific work, small fractions of a second are counted in milliseconds (thousandths), microseconds (millionths), nanoseconds (billionths), and sometimes smaller units of a second.

What is an example of a sub multiple of a unit?

Sub-multiple of Units Physicists often has to measure very small objects or amounts. When scientists do this they often use a prefix to the SI unit to indicate the fraction of the unit. Example The length of your mobile phone might be 0.145 m, but we would normally write as 14.5 cm.

#### What is the symbol for SI units?

Each SI unit has a specific symbol, which is the same in all languages. For example, in Irish the word for kilogram is ‘cileagram’, but the symbol is kg.
