information clearly. This system of measurement is called the International System of Units (SI). Metric measurement is based on the number ten and makes calculations with the system relatively easy. By using the following conversion chart, converting from one unit to another is done simply by moving the decimal point:
You will need to create a ratio (conversion factor) between the units given and the units needed. Ask yourself which unit is bigger. Put a "1" by that unit. Then ask how many of the smaller units are in the bigger unit. Put that number in front of the smaller unit. There is your conversion factor.
This free quiz helps you practice converting between SI (metric system) prefixes as well as a wide variety of dimensional analysis problems.
Step 1: Set up the ratio → ( 1 mg / 0.001 g) ÷ (x / 1 g) Step 2: Cross multiply → ( 1 mg)(1 g) = (0.001 g)(x) Step 3: Isolate x → ( 1 mg)(1 g) / (0.001 g) = x. Step 4: Divide and cancel → 1 mg / 0.001 = x → x = 1000 mg. : here are 1000 mg in 1 g 11. How man.
Converting between units with different prefixes: The most systematic way to convert units from one prefix to another is to go through the base unit, and use two conversion factors.
Any relationship between two units can potentially be utilized as a conversion factor: density relates mass and volume while molar mass relates moles and mass. Express these
1. Decide what form of the conversion factor to use: g/mL or the reciprocal, mL/g. Always begin by arranging the factors using units only. As the answer will contain one unit, begin with one unit, in this case, kg. 2. Insert the appropriate numerical values for each conversion factor. In order to cancel a mass and convert to a
