The RDA for trace element selenium is 0.000070 g/day is equivalent to 0.070 g/day
Further Explanation
Mass
- Mass refers to the quantity of matter in an object. Mass is measured using a beam balance.
S.I units
- The S.I. units of mass is grams. However, mass can be measured using other units such as milligrams, grams, kilograms etc.
Metric system unit of measurement
- It is a system of measurement that uses units such as gram, liter, and meter to measure mass, capacity and length respectively.
- This system measures mass based on grams, such that all the other units of mass are based on an inter-conversion of units in grams.
Conversion of units measuring length
1 gram = 1000 milligram
1 kilogram = 1000 grams
1 kilogram = 1000000 milligrams
1 tonne = 1000 kilograms
Conversion of larger units to small units
- To convert larger units of measurement to smaller units we multiply we multiply the number of larger units by the appropriate conversion factor.
Conversion of smaller units to larger units
- When converting smaller units of measurements to larger units of measurements we divide the number of smaller units by the appropriate factor.
In the question;
The mass of selenium is 0.000070 g/day
But, 1 gram= 1000 milligram
Thus;
0.000070 grams will be equivalent to;
= 0.000070 x 1000
= 0.070 g
The RDA for trace element selenium is 0.000070 g/day is equivalent to 0.070 g/day
