STUDY MATERIAL
What is Measurement?
English
Measurement means finding the length, weight, or capacity of an object using standard units.
We measure things every day.
Examples:
- Measuring height
- Buying vegetables
- Filling a water bottle
- Stitching clothes
हिन्दी
मापन (Measurement) का अर्थ है किसी वस्तु की लंबाई, भार या क्षमता को मानक इकाइयों में मापना।
हम प्रतिदिन कई चीज़ों का मापन करते हैं।
उदाहरण:
- ऊँचाई मापना
- सब्ज़ी खरीदना
- पानी की बोतल भरना
- कपड़े सिलना
Types of Measurement
There are three main types:
- Length (लंबाई)
- Weight/Mass (भार)
- Capacity (क्षमता)
1. Measurement of Length
