Unit Conversions

Why Convert Units?

  • To express measurements in a more convenient or familiar unit
  • To compare values between different systems of measurement
  • To perform calculations and solve problems involving different units

Types of Unit Conversions

  • Length:
    • Meter (m) to/from:
      • Centimeter (cm): 1 m = 100 cm
      • Millimeter (mm): 1 m = 1000 mm
      • Kilometer (km): 1 km = 1000 m
  • Weight/Mass:
    • Gram (g) to/from:
      • Milligram (mg): 1 g = 1000 mg
      • Kilogram (kg): 1 kg = 1000 g
  • Volume:
    • Liter (L) to/from:
      • Milliliter (mL): 1 L = 1000 mL
      • Cubic centimeter (cm³): 1 L = 1000 cm³
  • Time:
    • Second (s) to/from:
      • Millisecond (ms): 1 s = 1000 ms
      • Minute (min): 1 min = 60 s
  • Temperature:
    • Celsius (°C) to/from:
      • Fahrenheit (°F): °F = (°C × 9/5) + 32
      • Kelvin (K): K = °C + 273.15

Conversion Steps

  1. Identify the original unit and the desired unit
  2. Choose the correct conversion factor
  3. Multiply or divide the original value by the conversion factor
  4. Simplify the result and express it in the desired unit

Tips and Tricks

  • Memorize common conversion factors
  • Use dimensional analysis to check your work
  • Convert units in steps, if necessary (e.g., cm to m to km)

Unit Conversions

  • Unit conversions are necessary to express measurements in a more convenient or familiar unit, compare values between different systems of measurement, and perform calculations involving different units.

Types of Unit Conversions

Length

  • 1 meter (m) is equal to 100 centimeters (cm) or 1000 millimeters (mm)
  • 1 kilometer (km) is equal to 1000 meters (m)

Weight/Mass

  • 1 gram (g) is equal to 1000 milligrams (mg) or 0.001 kilograms (kg)
  • 1 kilogram (kg) is equal to 1000 grams (g)

Volume

  • 1 liter (L) is equal to 1000 milliliters (mL) or 1000 cubic centimeters (cm³)

Time

  • 1 second (s) is equal to 1000 milliseconds (ms) or 1/60 minute (min)
  • 1 minute (min) is equal to 60 seconds (s)

Temperature

  • Celsius (°C) to Fahrenheit (°F): °F = (°C × 9/5) + 32
