Convert architectural and engineering units online. Use these converters to convert angles, length, and areas. Choose between imperial or metric units or convert imperial to metric and vice versa.
Convert angle units
The units used to measure angles are degrees (° or deg), percent (%), and radians (rad). Make sure that you are not confused with difference between angles and slopes. Use these calculators to convert:
DEGREES (°) to PERCENT (%)
PERCENT (%) to DEGREES (°)
DEGREES (°) to RADIANS (rad)
RADIANS (rad) to DEGREES (°)
PERCENT (%) to RADIANS (rad)
RADIANS (rad) to PERCENT (%)
Convert slopes
The units used to measure slopes are rise over run ratio (rise : run), percent (%), and degrees (° or deg). Use these calculators to convert:
DEGREES (°) to PERCENT (%)
PERCENT (%) to DEGREES (°)
PERCENT (%) to RATIO
RATIO to PERCENT (%)
DEGREES (°) to RATIO
RATIO to DEGREES (°)
Calculate rise height from slope and run length
Calculate run length from slope and rise height
Convert lengths
The metric units used to measure lengths are millimeter (mm), centimeter (cm), meter (m), etc. The imperial units used to measure lengths are inch (” or in), foot (‘ or ft), yard (yd), mile (mi), etc. Use these calculators to convert:
Metric lengths.
Imperial lengths.
Metric to imperial lengths.
Imperial to metric lengths.
Convert areas
The units used to measure areas are square meter (m²), square feet (ft²), etc. Use these calculators to convert:
Square Meters to Square Feet.
Square Feet to Square Meters.
