In the metric system, "dam" is the symbol for decametre (sometimes spelled "dekameter"), which is a unit of length equal to 10 meters.
Decametre: A Closer Look
A decametre represents a multiple of the base unit of length, the metre. The prefix "deca-" indicates a factor of ten. Therefore:
- 1 dam = 10 meters
Understanding SI Prefixes
The International System of Units (SI) uses prefixes to denote multiples and submultiples of base units. "Deca-" is one such prefix, signifying multiplication by 10. Here are a few common prefixes:
| Prefix | Symbol | Factor |
|---|---|---|
| deca- | da | 101 |
| hecto- | h | 102 |
| kilo- | k | 103 |
| deci- | d | 10-1 |
| centi- | c | 10-2 |
| milli- | m | 10-3 |
Practical Use
While not as commonly used as meters, kilometers, or centimeters, the decametre can be useful in certain situations, particularly when dealing with lengths that are conveniently expressed as multiples of ten meters.
Summary
"dam" represents decametre in the metric system, a unit of length equivalent to 10 meters. It utilizes the "deca-" SI prefix, indicating a multiple of ten of the base unit.
