Convert a measurement
Pick the units, type the number, and use the swap button to go the other way. Results are rounded to 3 decimals.
- ft ↔ m, m ↔ yd, ft ↔ yd, in ↔ mm, mm ↔ ft
- Feet and inches (10 ft 6 in) ↔ metres
- sq ft ↔ m², m² ↔ sq yd, sq ft ↔ sq yd
Metres = Feet × 0.3048
12 ft × 0.3048 = 3.658 m
1 ft = 0.3048 m (exact)
Room size to panel area
Type the inside length, width and height in feet or metres. You get the wall and roof area in both square metres and square feet.
- Walls2 × (L + W) × H = 2 × (20 + 15) × 10
- 700sq ft65.032 m²
- Roof / ceilingL × W = 20 × 15
- 300sq ft27.871 m²
- Walls + roofGross, before doors and wastage
- 1,000sq ft92.903 m²
Wall area = 2 × (L + W) × H · Roof area = L × W
Square metres = Square feet ÷ 10.7639
For the panel calculator (metres): 6.096 × 4.572 × 3.048 m
Panel thickness in inches
Panels are sold by millimetre thickness. Tap a size to see it in inches.
Inches = Millimetres ÷ 25.4
100 mm ÷ 25.4 = 3.937 in
1 in = 25.4 mm (exact)

Conversion questions
The same constants as the converter and the formula card.
How do I convert feet to metres?
Multiply feet by 0.3048 (exact). Example: 12 ft × 0.3048 = 3.658 m.
How do I convert metres to feet?
Multiply metres by 3.28084. Example: 3 m × 3.28084 = 9.843 ft.
How do I convert square feet to square metres?
Divide square feet by 10.7639, because 1 m² = 10.7639 sq ft. Example: 1,000 sq ft ÷ 10.7639 = 92.903 m².
How do I convert square metres to square feet?
Multiply square metres by 10.7639. Example: 24 m² × 10.7639 = 258.334 sq ft.
How do I convert metres to yards and feet to yards?
One yard is 0.9144 m (exact), so 1 m = 1.09361 yd. One yard is 3 ft, so divide feet by 3: 12 ft ÷ 3 = 4 yd.
How do I convert square yards?
1 sq yd = 9 sq ft = 0.836127 m², and 1 m² = 1.19599 sq yd.
How do I convert 10 ft 6 in to metres?
Turn the inches into feet first: 6 ÷ 12 = 0.5, so 10.5 ft × 0.3048 = 3.2 m.
What is 100 mm panel thickness in inches?
Divide millimetres by 25.4 (1 in = 25.4 mm exact): 100 mm ÷ 25.4 = 3.937 in.
