## Angles

This calculator is based on conversion of two angle units. An angle consists of two rays (as in sides of an angle sharing a common vertex or else called the endpoint.) Some belong to rotation measurements - spherical angles measured by arcs' lengths, pointing from the center, plus the radius. For a whole set of multiple units of angle on one page, try that Multiunit converter tool which has built in all angle unit-variations. Page with individual angle units.

# Converter type: angle units

This online angle from '' into Ø dia- part converter is a handy tool not just for certified or experienced professionals.

First unit: second of arc ('') is used for measuring angle.

Second: diameter part (Ø dia- part) is unit of angle.

## 0.00029 Ø dia- part is converted to 1 of what?

The diameter parts unit number 0.00029 Ø dia- part converts to 1 '', one second of arc. It is the EQUAL angle value of 1 second of arc but in the diameter parts angle unit alternative.

How to convert 2 seconds of arc ('') into diameter parts (Ø dia- part)? Is there a calculation formula?

First divide the two units variables. Then multiply the result by 2 - for example:

0.000290888208666 * 2 (or divide it by / 0.5)

**QUESTION**:

1 '' = ? Ø dia- part

**ANSWER**:

1 '' = 0.00029 Ø dia- part

## Other applications for this angle calculator ...

With the above mentioned two-units calculating service it provides, this angle converter proved to be useful also as a teaching tool:

1. in practicing seconds of arc and diameter parts ( '' vs. Ø dia- part ) values exchange.

2. for conversion factors training exercises between unit pairs.

3. work with angle's values and properties.

International unit symbols for these two angle measurements are:

Abbreviation or prefix ( abbr. short brevis ), unit symbol, for second of arc is:

Abbreviation or prefix ( abbr. ) brevis - short unit symbol for diameter part is:

**Ø dia- part**

### One second of arc of angle converted to diameter part equals to 0.00029 Ø dia- part

How many diameter parts of angle are in 1 second of arc? The answer is: The change of 1 '' ( second of arc ) unit of angle measure equals = to 0.00029 Ø dia- part ( diameter part ) as the equivalent measure for the same angle type.

In principle with any measuring task, switched on professional people always ensure, and their success depends on, they get the most precise conversion results everywhere and every-time. Not only whenever possible, it's always so. Often having only a good idea ( or more ideas ) might not be perfect nor good enough solution. If there is an exact known measure in '' - seconds of arc for angle amount, the rule is that the second of arc number gets converted into Ø dia- part - diameter parts or any other angle unit absolutely exactly.
