Class 11 Conversion from one measure to another- In Class 11, the topic of conversion from one unit of measurement to another is typically covered in subjects like physics and mathematics. The conversion of units is essential in solving problems involving physical quantities and is fundamental to understanding various concepts in these subjects.
Here’s a general overview of the common units and their conversions:
- Length:
- 1 meter (m) = 100 centimeters (cm)
- 1 kilometer (km) = 1000 meters
- Mass:
- 1 kilogram (kg) = 1000 grams (g)
- 1 gram (g) = 1000 milligrams (mg)
- Time:
- 1 second (s) = 1000 milliseconds (ms)
- 1 minute = 60 seconds
- 1 hour = 60 minutes
- Temperature:
- Celsius to Kelvin: K = °C + 273.15
- Kelvin to Celsius: °C = K – 273.15
- Volume:
- 1 liter (L) = 1000 milliliters (mL)
- 1 cubic meter (m³) = 1000 liters
- Area:
- 1 square meter (m²) = 10,000 square centimeters (cm²)
- Speed:
- Speed = Distance/Time
- Density:
- Density = Mass/Volume
When converting units, always pay attention to the given unit and the desired unit. Use conversion factors to multiply or divide the quantity appropriately to get the desired unit.
For example, if you have a distance given in kilometers and you want to convert it to meters, you can use the conversion factor 1km=1000m. If you have a mass in grams and want to convert it to kilograms, you can use the conversion factor 1kg=1000g.
Here’s a simple example:
Example: Convert 3 kilometers to meters.
Solution: 3 km×1000 m/km=3000 m3km×1000m/km=3000m
Always make sure to cancel out the units appropriately, leaving you with the desired unit. Understanding and applying these unit conversion principles will be crucial throughout your studies in physics and related fields.
