What do I need help with?
- Metric System: The metric system is a system of measurement that is based on the decimal system, with units arranged in powers of 10.
- Metric system as powers of 10: The metric system is based on powers of 10, meaning that each unit is 10 times larger or smaller than the units adjacent to it. For example, 1 kilometer is equivalent to 1000 meters, or 1 centimeter is equivalent to 0.01 meters.
- Common US measures and conversions: This refers to the standard units of measurement used in the United States, such as inches, feet, pounds, and gallons. Conversions between these units are often necessary, such as converting inches to feet or pounds to kilograms.
1. Converting 1.000 m/s to mi/h:
First, convert meters to miles: 1 meter = 0.000621371 miles
1.000 m/s * 3600 s/hr = 3600 m/hr
3600 m/hr * 0.000621371 mi/m = 2.23694 mi/hr
2. Convert weight from pounds to kilograms and grams:
Weight in pounds: 2.205 lb = 1 kg
2.146 * 2.205 = 4.729 kg
1 kg = 1000 g
4.729 kg * 1000 = 4729 g
3. Write the number 62360 in e notation:
6.2360 x 10^4
4. Write 3.443 x 10^-7 in standard notation:
0.0000003443
