1. Unit of Measurement kya hota hai?

Unit of Measurement (UOM) ka use kisi bhi Stock Item ki quantity ko measure aur record karne ke liye kiya jata hai.

Simple words mein:

Unit of Measurement batata hai ki product ko kis unit mein count ya measure kiya jayega.

Jaise:

Product	Unit
Laptop	Nos
Keyboard	Nos
Rice	Kg
Mobile Cable	Nos
Cloth	Meter
Petrol	Litre
Paper	Ream
Water	Litre

Agar DSD Computers ke paas 50 keyboards hain, to Tally mein quantity 50 Nos ke form mein record ki ja sakti hai.

2. Unit of Measurement ki Need

Inventory maintain karte waqt sirf product ka naam sufficient nahi hota. Uski quantity aur measurement unit bhi important hoti hai.

For example:

Laptop = 20

Yeh clear nahi hai ki 20 kya?

• 20 Nos?
• 20 Kg?
• 20 Boxes?

Isliye Tally mein Stock Item ke saath proper Unit define ki jati hai.

Example:

Dell Laptop → 25 Nos

RAM → 100 Nos

Rice → 500 Kg

Cable → 200 Meter

3. Common Units of Measurement

Business ke according different units use ki ja sakti hain.

Unit	Meaning	Example
Nos	Numbers	Laptop – 10 Nos
Kg	Kilogram	Rice – 50 Kg
Gram	Gram	Spice – 500 Gram
Litre	Litre	Oil – 20 Litre
Meter	Meter	Cable – 100 Meter
Box	Box	Keyboard – 10 Box
Dozen	12 Pieces	Pen – 5 Dozen
Pair	2 Pieces	Shoes – 20 Pair
Set	Complete Set	Computer Set – 10 Set

4. Types of Units in Tally Prime

Tally Prime mein generally units ko do important categories mein samjha ja sakta hai:

1. Simple Unit

Ek single measurement unit.

Examples:

• Nos
• Kg
• Litre
• Meter

2. Compound Unit

Do simple units ko combine karke banaya gaya unit.

Example:

1 Box = 10 Nos

Yahan:

• Box = higher unit
• Nos = lower unit

Compound Unit useful hota hai jab business mein goods ko Box, Dozen, Carton etc. mein purchase/sell kiya jata hai, lekin stock actual pieces mein bhi track karna ho.

5. Simple Unit kya hota hai?

Simple Unit ek basic measurement unit hoti hai jo directly quantity ko represent karti hai.

Examples:

Laptop → Nos

Agar 15 laptops hain:

15 Nos

Rice → Kg

Agar 100 kg rice hai:

100 Kg

Cable → Meter

Agar 250 meter cable hai:

250 Meter

Memory Trick

One Product + One Measurement = Simple Unit

6. Compound Unit kya hota hai?

Jab do simple units ko combine karke quantity ko represent kiya jata hai, use Compound Unit kaha jata hai.

Example:

1 Box = 10 Nos

Agar business ke paas:

5 Box

hain, to total quantity:

5 × 10 = 50 Nos

Practical Example

DSD Computers keyboard ko box mein purchase karta hai.

1 Box = 20 Keyboards

Purchase:

5 Boxes

Total stock:

5 × 20 = 100 Keyboards

7. Tally Prime mein Unit Create Karna

Unit create karne ke liye generally:

Gateway of Tally → Create → Unit

Ya:

Alt + G → Create Master → Unit

Tally version/configuration ke according menu wording thodi different ho sakti hai.

8. Simple Unit Create Karne ke Steps

Suppose humein Nos unit create karni hai.

Step 1

Tally Prime open karein.

Step 2

Apni company select karein.

Step 3

Go to:

Gateway of Tally → Create → Unit

Step 4

Unit Creation screen open hogi.

Step 5

Select:

Type = Simple

Step 6

Unit details enter karein.

Example:

Field	Value
Type	Simple
Symbol	Nos
Formal Name	Numbers
Decimal Places	0

Step 7

Ctrl + A press karke save karein.

9. Decimal Places kya hota hai?

Decimal Places decide karta hai ki quantity mein decimal values kitni digits tak show hongi.

Example:

Agar decimal places:

0

hai:

10 Nos

Agar decimal places:

2

hai:

10.50 Kg

Example

Weight-based products mein decimal quantity useful ho sakti hai.

10.50 Kg

Lekin laptop ke liye normally:

10 Nos

use kiya jayega.

Easy Trick

Piece counting → Usually 0 decimal
Weight/measurement → Decimal ki need ho sakti hai

10. Compound Unit Create Karna

Suppose:

1 Box = 10 Nos

To Compound Unit create karke Tally ko quantity relationship batayi ja sakti hai.

Example:

Box of 10 Nos

Agar:

3 Box

sell kiye:

3 × 10 = 30 Nos

Isse inventory quantity ko properly track karna easy ho jata hai.

11. Stock Item ke saath Unit ka Use

Unit create karne ke baad Stock Item create karte waqt us unit ko select kiya jata hai.

Example:

Stock Item

HP Keyboard

Unit

Nos

Opening Balance

50 Nos

Ab Tally inventory mein keyboard ka stock Nos mein maintain karega.

12. Practical Example — DSD Computers

DSD Computers ke paas following products hain:

Stock Item	Unit	Opening Stock
Dell Laptop	Nos	20
HP Keyboard	Nos	50
Mouse	Nos	75
LAN Cable	Meter	500
Printer Ink	Nos	30

Ab jab purchase/sales entry ki jayegi, quantity selected unit ke according record hogi.

Example 1 — Purchase

DSD Computers purchased:

10 Dell Laptops

Entry:

Purchase → Dell Laptop → 10 Nos

Stock increase:

20 + 10 = 30 Nos

Example 2 — Sales

DSD Computers sold:

5 Dell Laptops

Stock:

30 − 5 = 25 Nos

13. Unit aur Stock Item ka Relationship

Is concept ko simple way mein samjho:

Stock Group
↓
Stock Item
↓
Unit of Measurement
↓
Quantity

Example:

Computer Accessories
↓
Keyboard
↓
Nos
↓
100 Nos

14. Unit of Measurement ke Benefits

1. Accurate Stock Quantity

Products ki exact quantity maintain hoti hai.

2. Easy Purchase Entry

Purchase ke time correct quantity enter karna easy hota hai.

3. Easy Sales Entry

Sales ke time product quantity properly record hoti hai.

4. Better Stock Reports

Stock reports mein quantity clearly show hoti hai.

5. Different Measurement

Different products ke liye different units use kar sakte hain.

6. Compound Quantity Management

Box, carton, dozen etc. ke through stock manage karna easier hota hai.

15. Unit vs Stock Item

Unit	Stock Item
Measurement batata hai	Product batata hai
Nos, Kg, Litre, Meter	Laptop, Mouse, Keyboard
Quantity measure karta hai	Actual inventory represent karta hai
Example: Nos	Example: Dell Laptop

Easy Memory Trick

Item = Kya hai?
Unit = Kitna hai?

Example:

Laptop = Item
Nos = Unit
20 = Quantity

16. Practical Classroom Activity

Students Tally Prime mein following units create karein:

Simple Units

1. Nos
2. Kg
3. Litre
4. Meter
5. Box

Phir following Stock Items create karein:

Stock Item	Unit
Laptop	Nos
Keyboard	Nos
Rice	Kg
Cooking Oil	Litre
LAN Cable	Meter

Practical Task

1. Units create karein.
2. Stock Items create karein.
3. Opening Stock enter karein.
4. Purchase entry karein.
5. Sales entry karein.
6. Stock Summary check karein.

17. Common Mistakes

❌ Mistake 1

Product ke liye wrong unit select karna.

❌ Mistake 2

Kg wale product ko Nos mein maintain karna.

❌ Mistake 3

Decimal requirement ko ignore karna.

❌ Mistake 4

Compound unit ka conversion incorrectly define karna.

❌ Mistake 5

Stock Item create karne ke baad wrong unit assign karna.

18. Easy Memory Trick

U-Q-R

U = Unit
Q = Quantity
R = Record

Correct Unit → Correct Quantity → Correct Stock Record

Aur ek simple formula:

Stock Item + Unit + Quantity = Inventory Record
