Scale Conversion Calculator
Convert measurements between different scales for maps, models, blueprints, and architectural drawings. Calculate precise scale conversions instantly.
Step 1: Original Measurement
Understanding Scales
A scale of 1:100 means 1 unit on the drawing/model equals 100 units in real life. Architectural scales are commonly expressed as ratios like 1:50, 1:100, or 1:200.
Step 2: Target Scale
Scale Conversion Formula
Converted Value = Original Value × (Original Scale ÷ Target Scale). For example, 100mm at 1:100 scale becomes 50mm at 1:50 scale (100 × 100/50 = 50).

Scale Conversion Formula
Converted Value = Original Value × (Original Scale ÷ Target Scale)
This formula calculates how a measurement changes when converting between different scales. The scale factor determines whether the converted value is larger or smaller than the original.
