No Separate Unit Converter Any More. Welcome to Unit Freedom.

If you came here looking for a traditional Unit Converter plugin, we have good news: you don’t need one. Traditional layout-breaking widgets, clunky sidebars, and confusing pop-up calculators belong in the past. CalcsLive eliminates the need for an external converter by introducing Unit-aware Quantities directly into your product specifications.

Backed by a mathematically unified core engine, SI (Metric) and Imperial units are treated with equal parity and absolute consistency. There are no secondary hidden approximations or sloppy conversions — whether your data is entered in millimetres or inches, every Self-converting Quantity handles the math natively on the client side.

You and your visitors enjoy total Unit Freedom to toggle between regional standards seamlessly, building checkout confidence while preventively reducing returns.

• Gutenberg Block – Visual editor with live preview

Unit-aware Quantity Shortcodes

Three shortcodes cover the full range of product specification formats. All are free, client-side, and require no CalcsLive account:

Single Quantity — [calcslive_qty]

A single unit-aware value. Visitors click the unit label to switch to any compatible unit. Use for individual specs like weight, length, pressure, or temperature.

[calcslive_qty value=25.4 unit="mm"] → displays 25.4 mm with a dropdown to convert to inches, cm, feet, and more.

Quantity Pair — [calcslive_qty_pair]

Two linked values that convert in sync. Supports two formats:

• 2D dimensions — [calcslive_qty_pair values="10x20" unit="cm"] — both values convert together (e.g. product footprint L × W)
• Coordinates or range — [calcslive_qty_pair values="(10, 20)" unit="cm"] — for temperature ranges, coordinate pairs, or min/max specs

Both values update simultaneously when the visitor switches units — no mismatched pairs.

Quantity Triplet — [calcslive_qty_triplet]

Three linked values that convert in sync. Supports two formats:

• 3D dimensions — [calcslive_qty_triplet values="10x20x30" unit="cm"] — for L × W × H product dimensions
• 3D coordinates — [calcslive_qty_triplet values="(10, 20, 30)" unit="cm"] — for spatial specs or multi-axis ranges

All three values convert simultaneously, keeping dimensional specs coherent in any unit system.

Works With

Shortcodes and the Gutenberg block work inside any WordPress editor or plugin that renders standard shortcodes:

• WooCommerce product tabs – Add unit-aware specs or calculators to any tab using plugins like Custom Product Tabs for WooCommerce or YITH WooCommerce Tab Manager
• Elementor – Drop a Shortcode widget onto any product or landing page
• Divi – Use a Code or Text module with the shortcode
• WPBakery / Classic Editor – Paste shortcodes directly into any text area
• Any shortcode-aware plugin – If it renders [shortcodes], CalcsLive shortcodes work inside it

Buying Calculations: Reduce Returns, Increase Confidence

Technical products often require customers to determine the right size and the right quantity before purchase. Without guidance, they guess—leading to returns, exchanges, and frustration.

Buying Calculations solve this by embedding pre-purchase calculators directly on product pages:

• Sizing calculators – Help customers choose correct dimensions, capacity, or fit
• Quantity calculators – Calculate how many bags, sheets, or units are needed

Create Calculators Without Coding

Traditional product calculators require custom development. CalcsLive changes this:

• Create calculation logic using familiar technical data
• Turn it into an interactive, unit-aware calculator
• Embed on WordPress with a simple shortcode

From days of development to under one hour—no coding required.

Product teams, engineers, or office staff can create and deploy calculators themselves, shifting calculator creation from a development task to a content task.

How It Works

For unit-aware Quantities (free, no account):
1. Add to any page:
– Single quantity:
– [calcslive_qty value=25.4 unit="mm"], value input without quote
– [calcslive_qty value='25.4' unit="mm"], value input with ‘ ‘
– [calcslive_qty value="25.4" unit="mm"], value input with ” “
– Quantity pair:
– [calcslive_qty_pair values="10x20" unit="cm"] for 2D dimensions, or
– [calcslive_qty_pair values="(10, 20)" unit="cm"] for coordinates/range
– Quantity triplet:
– [calcslive_qty_triplet values="10x20x30" unit="cm"] for 3D dimensions, or
– [calcslive_qty_triplet values="(10, 20, 30)" unit="cm"] for 3D coordinates
2. Visitors click to convert between compatible units

For embedded calculators:
1. Create your calculator on CalcsLive
2. Get your embed token and set it in the plugin settings
3. Grab article ID and add [calcslive id="YOUR_ID"] to your product page
4. Customers use the calculator interactively

Third-Party Service

This plugin relies on the CalcsLive external service to display interactive calculations. When an embed is rendered, your visitor’s browser loads content directly from CalcsLive via an iframe.

What is sent:

• Your embed token and domain (included in the iframe URL)
• The article ID you specify in the shortcode or block

No visitor data (such as IP addresses, cookies, or personal information) is collected or sent to CalcsLive by this plugin. The iframe loads in the visitor’s browser like any standard embedded content.

Quick Start

Unit-Aware Specs and Product Buying Calculators are two independent features. Use either one, or both.

A: Unit-Aware Specs (Free, No Account)

Use unit-aware quantity shortcodes anywhere shortcode insertion is supported — product descriptions, pages, posts, WooCommerce tabs, page builders:

[calcslive_qty value=25.4 unit="mm"] — single quantity  
[calcslive_qty_pair values="10x20" unit="cm"] — 2D dimensions or coordinates  
[calcslive_qty_triplet values="10x20x30" unit="cm"] — 3D dimensions or coordinates

Visitors click the unit dropdown to convert between compatible units. No API key. No external service. Fully client-side.

B: Embed Buying Calculators (Requires CalcsLive Account)

1. Create your calculator at calcslive.com — no coding required
2. Get your embed token (Settings → CalcsLive in WordPress) and your article ID
3. Embed anywhere with: [calcslive id="YOUR_ARTICLE_ID"] or use the CalcsLive Gutenberg block

Customers interact with the calculator live on your product page — inputs update in real-time.

Unit-aware Quantity Shortcodes

No API key needed. These shortcodes render interactive values that visitors can click to convert between units:

Single value:
[calcslive_qty value=25.4 unit=”mm”] (value input without quote)
[calcslive_qty value=’25.4′ unit=”mm”] (value input with ‘ ‘)
[calcslive_qty value=”25.4″ unit=”mm”] (value input with ” “)

Value pair — 2D dimensions:
[calcslive_qty_pair values=”10×20″ unit=”cm”]

Value pair — 2D coordinates or range:
[calcslive_qty_pair values=”(10, 20)” unit=”cm”]

Value triplet — 3D dimensions (L x W x H):
[calcslive_qty_triplet values=”10x20x30″ unit=”cm”]

Value triplet — 3D coordinates:
[calcslive_qty_triplet values=”(10, 20, 30)” unit=”cm”]

Optional attributes:

• dp – Decimal places (default: 2)
• show_unit_arrow – Show/hide unit dropdown arrow (default: true)
