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
