What does caliber represent in firearms?

Caliber denotes the internal diameter of a gun barrel or is used as a multiple of that diameter to express barrel length.

Why use inch (US survey) units?

Inch (US survey) is used in legacy US geodetic, cadastral, and mapping datasets and is important for interpreting historical survey data.

Can I use this conversion for modern precision measurements?

Since the US survey inch differs slightly from the international inch, this conversion may not be ideal for very high precision needs.

What Is This Tool?

This converter allows users to change length measurements from caliber, a firearms and artillery term related to bore diameter and barrel length, into the US survey inch, a historic unit used for geodetic and cadastral surveys in the United States.

How to Use This Tool?

Enter the value measured in caliber [cl].
Select the input unit as caliber and the output unit as inch (US survey).
Calculate the equivalent length based on the conversion factor.

Key Features

Converts caliber units, which represent barrel bore diameters or length multiples, into US survey inches.
Uses a precise conversion rate to relate firearms measurements with legacy surveying units.
Supports interoperability between ballistics specifications and historical surveying data.

Examples

5 caliber equals 0.0499999 inch (US survey).
10 caliber equals 0.0999998 inch (US survey).

Common Use Cases

Specifying bore diameter for small arms and matching ammo size.
Describing barrel lengths in artillery or naval guns.
Converting historical land surveying and cadastral records using US survey units into firearm measurement context.

Tips & Best Practices

Understand that caliber is a dimensionless ratio that needs bore diameter context for length interpretation.
Use this conversion primarily for integrating firearm measurements with historical surveying data.
Be mindful that US survey inch slightly differs from the international inch when precision matters.

Limitations

Caliber is dimensionless and context-dependent; exact length depends on bore diameter knowledge.
The US survey inch is a legacy unit with minor differences from the international inch, possibly impacting precision.
This conversion presumes a strict definition of caliber as a length unit which can vary with actual firearm use.

Frequently Asked Questions
