CalcsLive brings Unit Freedom to technical quantities and calculations where they are needed.

For e-commerce, CalcsLive turns static product specifications into live unit-aware content. Add self-converting quantities such as dimensions, weights, pressures, temperatures, capacities, and 2D/3D product sizes directly inside WordPress or WooCommerce product pages.

Customers can read specs in the units they understand, switch between compatible units, and use embedded sizing or quantity calculators before they buy. This helps reduce confusion, support questions, wrong-size purchases, and preventable product returns.

Unit-aware quantity shortcodes are free and require no account. Embedding interactive buying calculators requires a CalcsLive account. See calcslive.com for plans.

Quick Start

Watch how easily you can create self-converting specifications and product level buying calculations without touching code:

** Unit-aware Quantity Shortcodes in Action **

** Unit-aware Buying Calculation in Action **

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 rendering is supported — product descriptions, pages, posts, WooCommerce tabs, page builders. No API key. No external service. Fully client-side.

Single quantity:
[calcslive_qty value=25.4 unit=”mm”]

Quantity pair:
— 2D dimensions: [calcslive_qty_pair values="10x20" unit="cm"]
— 2D coordinates or range: [calcslive_qty_pair values="(10, 20)" unit="cm"]

Quantity triplet:
— 3D dimensions (L x W x H): [calcslive_qty_triplet values="10x20x30" unit="cm"]
— 3D coordinates: [calcslive_qty_triplet values="(10, 20, 30)" unit="cm"]

Visitors click the unit label to convert between compatible units. The value attribute accepts quoted or unquoted numbers.

Optional attributes:

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

B: Embed Buying Calculators (Requires CalcsLive Account)

Create your calculator at calcslive.com — no coding required
Get your embed token (Settings CalcsLive in WordPress) and your article ID
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.

Beyond Unit Conversion: Unit Freedom

Traditional unit converter plugins add a separate conversion widget. That forces customers to copy numbers, switch context, and interpret product data outside the product description.

CalcsLive works differently. A product spec such as 25.4 mm, 10 x 20 x 30 cm, or 2.5 bar becomes a Self-converting Quantity in place. Visitors can switch to inches, feet, psi, pounds, gallons, or other compatible units without leaving the page.

For authors, this means you write correct quantities once. For readers, it means they are free to understand and compare the product in the units that make sense to them. That is Unit Freedom.

More Than a Calculator: Unit-Aware Calculation

Most calculator plugins compute numbers. CalcsLive computes physical quantities with units.

That matters for technical products because formulas should represent the real relationship, not a hard-coded unit system. A unit-aware calculator can accept inputs in metric, imperial, or mixed units and still produce consistent results.

Examples:

AC sizing from room dimensions
Concrete bag quantity from length, width, and depth
Belt sizing from pulley data
Cylinder force from pressure and bore diameter
Pump or flow calculations using customer-entered values

Perfect For

WooCommerce and e-commerce stores – AC sizing, concrete quantity, flooring coverage, paint calculators
Technical products – live unit-aware specifications such as mm inches, kg lb, psi bar
Building materials – “How many bags, sheets, rolls, or boards do I need?” calculators
Industrial equipment – belt sizing, cylinder selection, pump sizing, capacity calculators
Product documentation – interactive unit-aware specs inside technical articles and manuals

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

Third-Party Service

The unit-aware quantity shortcodes run client-side and do not require the CalcsLive service.

Embedded calculators rely on the CalcsLive external service. When an embed is rendered, the visitor’s browser loads calculator content directly from CalcsLive through an iframe.

What is sent for embedded calculators:

Your embed token and domain, included in the iframe URL
The article ID specified in the shortcode or block

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