• Surveying

With this tool, you can:

• Convert minutes to decimal
• Convert degrees minutes seconds (DMS) to decimal degrees
• Convert decimal to minutes

🔹 Understanding Minutes and Decimal Format

What Are Minutes?

Minutes can represent:

• Time (e.g., 2 hours 30 minutes)
• Angles (e.g., 40° 30′ 15″)

What Is Decimal Format?

Decimal format expresses values as a single number:

• 2.5 hours
• 40.5042°

🔹 How to Convert Minutes to Decimal (Time)

Formula:

$$\text{Decimal} = \text{Hours} + \frac{\text{Minutes}}{60}$$Decimal=Hours+60Minutes​

Example:

2 hours 30 minutes:$$2 + \frac{30}{60} = 2.5$$2+6030​=2.5

So, 2:30 = 2.5 hours

🔹 How to Convert Degrees Minutes Seconds to Decimal Degrees

Formula:

$$\text{Decimal Degrees} = \text{Degrees} + \frac{\text{Minutes}}{60} + \frac{\text{Seconds}}{3600}$$

Example:

40° 30′ 15″$$40 + \frac{30}{60} + \frac{15}{3600} = 40.5042°$$

So, 40° 30′ 15″ = 40.5042°

🔹 How to Convert Decimal to Minutes

Formula:

$$\text{Minutes} = \text{Decimal Part} × 60$$Minutes=Decimal Part×60

Example:

2.75 hours:$$0.75 × 60 = 45 \text{ minutes}$$0.75×60=45 minutes

So, 2.75 hours = 2 hours 45 minutes

🔹 Convert Hours and Minutes to Decimal (Excel Method)

In Excel, time values are often converted using:$$= \text{Hours} + \frac{\text{Minutes}}{60}$$=Hours+60Minutes​

Example:
3:15 → 3.25
