What is This Tool?

Specialized converters handle domain-specific conversions including fuel economy (MPG to L/100km), clothing sizes (shoe, ring), paper sizes (A4, Letter), angle measurements (degrees, radians), and Roman numerals. Each uses its own conversion system specific to its field.

Formula
Fuel: L/100km = 235.215 / MPG Angles: radians = degrees x pi/180 Roman: I=1, V=5, X=10, L=50, C=100, D=500, M=1000 (subtractive notation: IV=4, IX=9, XL=40, etc.)
Worked Examples

1. MPG to L/100km

Given: 30 MPG

L/100km = 235.215 / 30 = 7.84

Result: 7.84 L/100km

2. Degrees to Radians

Given: 180 degrees

radians = 180 x pi/180 = pi

Result: 3.14159 radians

3. Number to Roman Numeral

Given: 2024

2000 = MM, 20 = XX, 4 = IV

Result: MMXXIV
