Convert Centiares to Deciares

To convert centiares (ca) to deciares (da), use the fact that both are metric area units based on the are.

• 1 deciare (da) = 10 square meters (m²)
• 1 centiare (ca) = 1 square meter (m²)

That means 1 da = 10 ca, so a centiare is one-tenth of a deciare.

Conversion formula (centiares to deciares)

• da = ca ÷ 10
• da = ca × 0.1

Quick examples

• 50 ca = 50 ÷ 10 = 5 da
• 1 ca = 0.1 da
• 10 ca = 1 da

Use this centiare to deciare conversion any time you need to switch between ca and da for land area, plots, or metric area values.

How many centiares are in a deciare?

There are 10 centiares (ca) in 1 deciare (da).
This comes from the metric area scale: 1 da = 1/10 are, and 1 ca = 1/100 are.

How many deciares are in a centiare?

There are 0.1 deciare (da) in 1 centiare (ca).
That means 10 centiares make 1 deciare.

What is the formula to convert centiares to deciares?

Use this simple formula:
deciares = centiares ÷ 10

Example: 45 ca ÷ 10 = 4.5 da

What is the formula to convert deciares to centiares?

Use this formula:
centiares = deciares × 10

Example: 3.2 da × 10 = 32 ca

Are centiares and deciares part of the metric system?

Yes. Centiares and deciares are metric area units based on the are (a).
They scale by powers of 10, which keeps conversions easy.

What is a centiare (ca)?

A centiare is an area unit equal to 1 square meter (1 m²).
It also equals 0.01 are.

What is a deciare (da)?

A deciare is an area unit equal to 10 square meters (10 m²).
It also equals 0.1 are.

How do centiares and deciares relate to square meters?

They match square meters neatly:

• 1 ca = 1 m²
• 1 da = 10 m²

So converting between them is the same as moving between 1 m² and 10 m².

How do centiares and deciares relate to ares and hectares?

Here are the key links:

• 1 are (a) = 100 ca = 10 da = 100 m²
• 1 hectare (ha) = 100 a = 10,000 m²
• 1 ha = 10,000 ca = 1,000 da

Is converting centiares to deciares just moving the decimal point?

Yes. Since 1 da = 10 ca, you can divide by 10.
That moves the decimal one place left.

Example: 78 ca becomes 7.8 da.

What are common examples of centiares to deciares conversions?

Some quick conversions:

• 10 ca = 1 da
• 25 ca = 2.5 da
• 50 ca = 5 da
• 100 ca = 10 da
• 250 ca = 25 da

Why do land and lot sizes use centiares and deciares?

These units work well for land because they sit between square meters and larger units.
Centiares fit small areas, and deciares make medium areas easier to read.

Do centiares and deciares measure area or length?

They measure area, not length.
They describe surface size, like a yard, garden, field, or plot.

Can I convert centiares to deciares without changing the area?

Yes. The area stays the same. Only the unit changes.
It’s like writing the same distance in meters or centimeters.
