Percentage To Float

Two different scales, same slider, and everyone has tripped on it. When you're picking a denoise strength, an IP-Adapter weight, or a blending factor, a lot of nodes want 0.0 to 1.0. But the setting that lives in your head - and in half the UIs you've used - is a percentage, 0 to 100. Wire 35 into a socket that means 0.35 and you're silently running 100x the strength you wanted.

Percentage To Float exists to make that conversion a named, obvious thing instead of a "did I divide by 100 this time?" gamble.

How it works

It's one line under the hood: float_value = percentage / 100.0. Input percentage (a float, 0 to 100, default 0) becomes output float_value (0.0 to 1.0). That's the entire mechanism, and that's fine - the value of the node isn't the math, it's that the conversion is explicit and readable in your graph.

You'd think ComfyUI would have this built in, but the primitive/number tooling has historically been bare-bones, which is why utility packs keep shipping these. The Sage Utils philosophy here is the same as everywhere else in the pack: give the fiddly conversion a dedicated node so a workflow reads like intent, not arithmetic.

When it's worth using

• Hooking a human-readable "35%" slider up to a node that expects a fraction - denoise strength, blend weights, adapter strengths.
• Building metadata or prompt text where you want the percentage and the fraction to agree.
• Anywhere you're composing values through other utility nodes and don't want a mystery /100 buried in a formula string.

Honest talk: if you're comfortable with the division and never mix the scales up, you don't need this node. But "I mixed the scales up" is a remarkably common failure mode, and a named node in the middle of the wire makes the intent explicit for the next person (or future-you) reading the graph.

Inputs and output

• percentage - float, 0–100, default 0.
• float_value - the normalized 0.0–1.0 result.

Nothing optional, nothing hidden. It's as thin as a utility node gets.

Installation

Sage Utils install, same as the rest of the pack. ComfyUI Manager, search "Sage Utils", or:

cd ComfyUI/custom_nodes
git clone https://github.com/arcum42/ComfyUI_SageUtils
cd ComfyUI_SageUtils
pip install -r requirements.txt

Restart ComfyUI. Only dependency is dynamicprompts; no models, no extra compute.

A small thing to keep in mind: the widget clamps to 0–100, so you can't accidentally type 150 and get a nonsense 1.5 - the value is always a real percentage when it leaves the input. The node's job starts after that.
