Unit Switch

A unit switch that shows the converted value next to it: both numbers ship in the markup and CSS picks the one whose radio is checked.

# Install and place "buttongroup-045" (Unit Switch) from VibeUI

## 1. Install first — do not skip, do not recreate
Run this exact command before writing any code:
npx shadcn@latest add https://vibeui.ru/r/buttongroup-045.json

Registry item: https://vibeui.ru/r/buttongroup-045.json
Installs to: components/vibeui/buttongroup-045.tsx (the exact path follows this project's components.json aliases).
npm dependencies: none.
Registry dependencies: none.

Install it from the registry. Do not recreate it from the description,
do not substitute a similar component from another library, and do not
rewrite it to match the project's existing style.

## 2. What it is
A unit switch that shows the converted value next to it: both numbers ship in the markup and CSS picks the one whose radio is checked.

A compact unit switch beside a value that changes without JS. Zero dependencies, one file, a server component.

## 3. How to use it
import { Buttongroup045 } from "@/components/vibeui/buttongroup-045"

<Buttongroup045
  metricValue="18 °C"
  imperialValue="64 °F"
  caption="weekly average"
  defaultValue="metric"
/>

Read the installed file for the full prop list.

## 4. Where to place it
This is a small inline component. Put it exactly where the user asked,
inside the existing markup. Do not create a new page, section or
wrapper for it. If a similar control already sits in that spot,
replace it instead of adding a second one.

Placement: ___
(The user fills this line in. If it is still blank, ask where to put it
instead of guessing.)

## 5. Keep exactly as installed
- the local --vibeui-buttongroup-045-* palette — do not swap it for your theme tokens
- both values in the markup: converting in the browser drifts from the server's rounding
- the pinned width and tabular figures on the value — otherwise the cluster jumps on every switch
- keeping the value and the switch together: a unit without a number means nothing
- radios inside a fieldset, so the choice reaches the form and works with arrows
- the caption under the value: "18 °C" without "weekly average" does not say what the number is

## 6. You may change
- the unit captions through metricLabel and imperialLabel
- the displayed numbers through metricValue and imperialValue
- the caption under the value through caption
- the initial system through defaultValue, the field name through name and the accent through accent

## 7. Rules
- There are exactly two units: a third system needs its own display rule in the CSS.
- The values are ready-made strings: formatting and rounding are your code's job.
- The hidden value stays in the HTML: it is shipped even though it is not shown.
- Do not lift the CSS variables into globals.css: the component has to stay a single file.

## 8. Verify
- it renders with no console errors;
- it looks like the preview on the VibeUI page you copied this from;
- if it does not, you changed something listed in section 5 — put it back.

For developers

npx shadcn@latest add https://vibeui.ru/r/buttongroup-045.json
https://vibeui.ru/r/buttongroup-045.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в переменных --vibeui-buttongroup-045-*. Серверный: пересчёт делается на стороне, отдающей страницу, а не в браузере — поэтому округления и локали не расходятся. Оба значения лежат в разметке, и правило [data-vibeui-block]:has([data-unit="metric"] input:checked) [data-value="metric"]{display:inline} показывает нужное. Значение набрано табличными цифрами и имеет min-width:4.25rem, поэтому «18 °C» и «64 °F» занимают одно место. Сцепка компактная и стоит рядом со значением, а не отдельным блоком: единица без числа бессмысленна.

Component source

The same file your agent installs. Here in case you would rather copy it by hand.

import type { ComponentPropsWithoutRef, CSSProperties } from "react"

export type Buttongroup045Props = Omit<
  ComponentPropsWithoutRef<"fieldset">,
  "children"
> & {
  metricLabel?: string
  imperialLabel?: string
  metricValue?: string
  imperialValue?: string
  caption?: string
  defaultValue?: "metric" | "imperial"
  name?: string
  accent?: string
}

// Идея компонента: переключатель единиц, который тут же показывает результат
// пересчёта. Оба значения лежат в разметке, и выбранный radio показывает
// нужное правилом CSS — пересчёт делается на сервере при отдаче, а не в
// браузере, поэтому ни округления, ни локали не расходятся. Значение набрано
// табличными цифрами и имеет фиксированную минимальную ширину: «18 °C» и
// «64 °F» занимают одно место, и группа не дёргается при переключении.
// Сама сцепка компактная, потому что стоит рядом со значением, а не отдельно.
