Length and Measurement Converter
Our Length and Measurement Converter helps you switch between different units of length, whether you're working with metric (millimetres, centimetres, metres, kilometres) or imperial (inches, feet, yards, miles). This is useful for everything from DIY projects and cooking to understanding distances when travelling or studying science.
The UK uses a mix of metric and imperial units, which can sometimes be confusing. Knowing how to accurately convert between these systems is key to avoiding errors, especially when measurements need to be precise for tasks like cutting materials or following recipes from different countries.
How to Convert Feet to Metres
Find the conversion factor
To convert feet to metres, you need to know that 1 foot is equal to 0.3048 metres. This is a standard conversion factor.
Multiply by the factor
Take the number of feet you want to convert and multiply it by 0.3048. For example, if you have 15 feet, you would calculate 15 × 0.3048.
State your answer
The result of your multiplication is the length in metres. So, 15 feet converts to 4.572 metres.

Common mistakes to avoid
- Someone says: 'I need a 10 cm piece of wood, which is roughly 10 inches.':They are incorrectly assuming a 1:1 or similar simple relationship between centimetres and inches, forgetting the conversion factor. 10 cm is actually about 3.94 inches. An inch is much longer than a centimetre.
- A driver thinks: 'If I'm driving 50 miles, that's about 50 kilometres.':They are confusing miles with kilometres and not applying the correct conversion factor, which is roughly 1.6. 50 miles is approximately 80.47 kilometres. Kilometres are shorter than miles.
- A DIYer asks for '3 feet of rope' but means '3 yards of rope':They are mixing up feet and yards, which are both imperial units but have different lengths. One yard is three times longer than one foot. 3 yards of rope is actually 9 feet of rope. Always clarify which unit you mean.
Questions people ask
How many centimetres in an inch?
There are exactly 2.54 centimetres in one inch. This is a fixed conversion factor agreed internationally, making it easy to switch between imperial and metric measurements accurately.
How do I convert height from feet and inches to cm?
First, convert the total height into inches. Multiply the number of feet by 12, then add any remaining inches. Finally, multiply this total number of inches by 2.54 to get the height in centimetres.
What is the difference between a yard and a metre?
A yard is an imperial unit of length, equal to 3 feet or 36 inches. A metre is the base unit of length in the metric system. A metre is slightly longer than a yard, with 1 metre being approximately 1.094 yards.
Why do UK builders still use feet and inches?
Many UK builders and tradespeople continue to use feet and inches due to tradition and familiarity, especially when working on older properties. Tools, materials, and some building practices were historically based on imperial measurements, and this legacy persists.
